I have an avi that is 25 fps and I am trying to make a VCD. I tried both Canopus Pro and TMPEG to convert the avi to an NTSC VCD, but once its converted the audio plays about 5 seconds befor the video. How can I fix this?

U might try this..helped me quite a bit nandub

the audio was probably not made carefully enough...
The quick & easy fix is to re-interleave your AVI, using: probably NanDub would be best
http://prdownloads.sourceforge.net/ndub/nandub-binary-1.0rc2.rar
You need to set both audio and video to 'DIRECT STREAM COPY'.
Then use Save as AVI [F7]..under FILE to save your new AVI..on a diff drive or diff file on same drive
BELOW IS A METHOD FOR OUT OF SYNC AUDIO & VIDEO
You cannot SLOW the AUDIO down, instead you must increase or decrease the video framerate.
For example, if it is standard 23.976 you could change it to 23.984
There will be a recommended framerate listed, which will allow the audio and the video to finish
at the same time (which is what you want :)
But trial & error is the only sure way...
Ideally you will read the AVI from one drive, and write the new file to another.
If you have only one HD, try to read from one partition and write to another.
If you have only one partition, make sure you don't overwrite any files - make a different (destination)
folder.
By manipulating video framerate and advancing or retarding the start of the audio, there is no
messed-up AVI that cannot be fixed, or at least made more watchable.
