cant figure out this problem with DVD2SVCD

[grimm003]

ok, i did search and try a few things, but couldnt find any1 that had this problem. I just combined 3 mpeg4 format .avi's into 1 .avi, i used vegas video and well now i got this .avi that plays normal in wmp and vdub, but every time i try converting into svcd(i've tried 3 times already), the audio gets screwwy. the audio only plays for 11m22s and the video is over an hour. i opened the encoded_audio_1 file and its only 11:22 long. every time the audio seems to be the same length so i think some settings might be off. when i combined to 3 files it changed the framerate from 23.xx to 29.xx so i thought that might be it, but the audio isnt fast or slow, its just short. can any1 help?
