Stuttering issues after cutting video

[trooper11]

I have been using a single method for converting anime and cartoons to dvd using CCE and batch files. so far its done perfectly until I started on some invader zim episodes.

they all encode just fine and when i multiplex the resulting files with the audio which was converted to ac3, everything is in sync, etc.

the problem comes when i go to cut the opening/ending scenes. i use Mpeg Video Wizard for my cutting and ive never had a problem before with it. but everytime i make a cut in one of these episodes, the resulting clip stutters badly.

would this be the fault of the program or something corrupt in my encoded mpeg2 files? or even the ac3 audio files? maybe i left off a setting in CCE that would cuase this to crop up. thanks for any help

ok ive done some testing to narrow things down and it looks like its the ac3 stream that introduces the problem.

the cut videos that stutter during playback run smothly if i demulitplex the audio from the video.

i ran ac3fix but it didnt find any errors, so i dont know why the audio stream would cuase this. i created the ac3 file using the wav file i extracted from the source avi using virtualdubmod. i used ffmpeggui to convert the wav file to a 192 bitrate, 48000 sample rate ac3 file and each step didnt give any indications of errors.

ive done this countless times with other avi sources, what could be causing it now?

well i ended up finding the solution after all

it turns out that the avi sourc ei had used ac3 for its audio stream to begin with and i was saving it as a wav in vdub then trying to convert that back to ac3 lol, now i just extract the track and they work fine
