How to Convert AVI to DVD
Ok, so you've got this downloaded AVI (DiVX, XViD) movie and you want to watch it on your TV, but you dont have a DiVX DVD Player. I am going to show you how to convert this AVI movie to a DVDISO image with minimal to no quality loss of the movie file.
Tools Needed:
Tools Needed:
-AVI2DVD (here)
-CCE SP v2.67.00.27 (Search Torrents, found mine on ISOHUNT)
-DVD Decrypter (here) -DVD Burner
Step One: Install all software listed above.
Step Two: Start up AVI2DVD and load .AVI file.

Step Three: Choose Output
Here is where you choose the format you want the video to be encoded into.(VCD,SVCD,DVD5,DVD9) Here we are going to choose DVD-5.

Step Four: Choose Encoder
This is the step where we choos the encoder we wish to use to convert our files. (1)When you get to this step Click Locate CCE and browse for the CCE SP exe file and click Open. Verify that the bar above the passes box is Green and says CCE Found! If it says this your all set.
The amount of passes you use is completely up to you, I recommend using 5 or more passes if video is under 100 mins. 6 or more for anything over 100 mins. The more passes the better quality DVD you will get. Maximum passes allowed is 9.

Step Five: Enocding Time!
This is the longest step in the whole process. Time for full encode depends on how many passes you chose. Each pass takes about an hour.
Clcik Add Job, in the box right under that button, Job Queue, Job 1: (filname) should have appeared. Now clcik the GO !!! button. After clicking GO !!! a box like this will appear:

Click Proceed. After clicking Proceed 2 Command Prompt Boxes will appear after a while (usually 30 to 60 seconds after) that look similar to this:

DO NOT close them, they are encoding the audio to AC3 format for use on the DVD. (The box pictured is the first one to appear. after that one goes away the second one comes up). After the second dialog box disappears this should come up:

Click Apply Then Click OK. After clicking OK you should get:

This box will be up for a while...so sit back, relax and let it do its job. First it will do an INFO pass, then it will do the number of video passes you chose.
After the last encoding pass finishes, these next four command prompt boxes show up one at a time:




After those are all gone and your back to the AVI2DVD screen you're done for this step!!
Step Six: Burning the ISO
The last step....your almost there.
Open DVD Decrypter.
Clcik Mode > ISO > Write and you should get:

Now just follow the instructions in the pic above, and when its done burning, congratulations! your done!
Now just pop the DVD in your player sit back and enjoy.

How to get unlimited bandwidth from your host for free
NOTE: This applies only to specific hosting companies, due to the
specific setup needed and does have its drawbacks.
While setting up hosting space with a specific company I often deal
with, I noticed that they used a shared IP. (IP shared by two or more
websites/domains.) Well, the rates for unlimited bandwidth were
around $50+ per month.
Back on track... When setting up the acct, the hosting company needs
to know the domain name so that they can direct it accordingly.
(example: 'http://www.123.4.567.890/~user1/ ,
'http://www.123.4.567.890/~user2/ etc)
At this point you can give a url that doesnt belong to you at all. As
long as the nameservers dont change, that should have absolutly no
negative effects on you or your site whatsoever.
How it works is this:
The host propogates you a certain amount space on its servers, and
monitors the traffic that enters their space through the domain its
registered under. Being that the domain isn't connected to the site
at all, it registers ZERO traffic.
Zero traffic registered = can't possibly go over bandwidth
restrictions
can't possibly go over bandwidth restrictions = free unlimited
bandwidth
Now the problems with this (besides the ethical ones) is that your
host may offer X amount of mail addys with the acct
(you@y...) and these will not work, as the name isnt on their
DNS. However, some domain companies allow you to set it up
regardless. Another problem seems to be strictly cosmetic, but can be
highly problematic... Once you attach the domain you want onto the
site, each page comes up/w the ip/UN the host propagated to your
acct. Its at this point where you have to have a phenominal 10-15
character alphanumerical or better (#, &, etc) pw, or your site will
be vulnerable to attack since the attacker already has your UN. This
only gives attackers a slight advantage as the amount of time it
would take to brute force a 10 character pw @ a rate of 1,000,000 per
second is 10 years. Add numbers and case sensitivity to that and it
becomes approx 26,980 years.
While I'm on it, I may as well add that if you use this method,
obviously you are going to be using the lowest cost hosting plan
available, which in turn will offer the least amount of space. Thats
why free hosts were invented.
Free hosts suck as a general rule. Who wants a site smothered in ads?
However, if you upload all your programs, graphics and other large
files (have a backup of course) to a reliable free host and target
them accordingly from your site you have just freed up a signifigant
amount of space. The only setback/w this is having to keep an index
card or file around/w your pws, as you should never use the same one
twice, and want to use complicated ones.

How To Fix Corrupt Files
Large downloads often seem to become corrupted due to one or more of the following reasons:
* Bug in the download manager.
* Bad proxy server.
* Bad web server.
* Problems with your own computer.
Re-downloading corrupted files, specially those sized over 500 MB are really painful for most of us. And there is no guarantee that the re-downloaded file will be free of corruption as far as you are using the same configuration.
In such cases, its best to fix them manually instead of downloading again. The whole process is very simple, but requries enough concentration. Once you have mastered it, you will never have to worry about corrupted files.
Tools Required:
* WinHex
* CURL
Steps required in brief:
* Make a backup copy of the corrupted file and open it with WinHex.
* Identify corrupted segments. Large sequences of zeros are all we have to search for in most cases.
* Re-download the corrupted segments with CURL.
* Write the retrieved data on appropiate offsets.
Step-by-step example:
Let us assume that we have a corrupted file named corrupted.rar. We open it WinHex, and do the following things:
* Switch the offset representation from hex to decimal by clicking once on the offset area

Now we search for corrupted segments. Most of the time they will be sequences of zeros. As we can see from the first bytes of the opened file, it's a rar file. Files we download over the Internet are mostly compressed formats. By design, a fresh file should not contain sequences of zeros or other repeating bytes after the header part. So, we scroll a few pages down.

Now we start searching for such sequences with CTRL+ALT+F.

The search takes us to a place where we can see some zeros and repeating bytes. Surely this is one of the corrupted segments.

So, now we have to download the missing data using CURL. It's always a good idea to retrieve the data with some margin. In our case, we get the bytes from 01094304 to 01094512 in order to cover the screenshot size. In real case it should be even higher. So, we start command prompt and issue the command "curl -r 1094304-1094512 http://badserver.com/mygoodfile.rar -o 01094304.bin" to download the mentioned segment of the original file, and save it to a file named 01094304.bin. For details, curl manual can help. After it's done, curl will terminate and we will have our file 01094304.bin right inside CURL's folder.

# Now we open the downloaded segment 01094304.bin with WinHex.
# Copy the whole file with CTRL+A -> CTRL+C.

Switch back to our corrupted file and go to the starting offset of our retrieved segment. CTRL+G -> 01094304

Now press CTRL+B to write the copied data over this offset. It is very important to determine correct offset. One offset left or right can ruin everything. Our retrieved segment starts with 18 1E BD 3D, and the offset we are going to write here also starts with 18 1E BD 3D.

* After we are done, we save the file using CTRL+S. For larger files, it is better to switch the edit mode to in-place mode. F6 -> In-place mode.
Now we can see that the corrupted part has been filled with original data, and it's fixed. In this example we had only of such segment. But in real cases, there might be several segments like this. In that case the whole procedure is to be repeated for each corrupted segment. Also note that, the length of zero sequences to find for can be chosen to be smaller or larger than the length used here.
* Bug in the download manager.
* Bad proxy server.
* Bad web server.
* Problems with your own computer.

* After we are done, we save the file using CTRL+S. For larger files, it is better to switch the edit mode to in-place mode. F6 -> In-place mode.
Now we can see that the corrupted part has been filled with original data, and it's fixed. In this example we had only of such segment. But in real cases, there might be several segments like this. In that case the whole procedure is to be repeated for each corrupted segment. Also note that, the length of zero sequences to find for can be chosen to be smaller or larger than the length used here.
