Here's my problem, I have several AVI files that won't fully convert to MPEG-4. The original file size is around 170mb, but when I check the output folder, the MPEG-4 file is around 60 or 80kb; and when I go to play the files, their length is only about 10 minutes instead of about 24. I've tried converting with Videora and Free Ipod Converter with basically the same results, only Videora converts it to a file with 80kb while the other only converts to about 60. Can anyone help me?
