audio out of sync after split, ripple delete

i'm hoping this is not a hardware issue because i saw the same exact problem in Premier Elements 2..
while editing out commercials, i end up doing multiple splits and ripple deletes. it seems the more edits i make while going further into the video, the more the audio becomes out of sync with the video. anybody experience this?? is there maybe a fix for it already that i haven't installed yet?? obviously, VMS is unusable if i can't get around this..

How was your video footage aquired? This is frequently seen with various consumer MPEG2 capture cards (as opposed to capturing the video footage in DV AVI files).

through ADS Tech's DVD Express/CapWiz saving them as mpeg2 files. they always worked fine in Pinnacle. i figure if there's any place where they wouldn't work it would be there given all the other problems it has..
anyway to get around it?? i know that Pinnacle can take an mpg file and rerender it as an AVI because i had to do it in order to use VMS' trial edition (no mpg2 encoding). you think that'll do it??

OK, this is going to be maybe a bit messy; perhaps someone else has another suggestion.

Option 1: See if your capture card will capture to some other format than MPEG-2; MPEG-2 is a delivery format, not an editing format, and as a result is difficult for many editors to work with.

Option 2: Convert the MPEG-2 file into DV AVI, edit with the DV AVI in VMS. You might try "Render As..." in VMS with an AVI/NTSC DV template.

Option 3: Demux the MPEG-2 file audio and video into seperate files, then re-mux the video file with an empty audio strea (giving you a video program stream to use in VMS, since I don't think it supports elementary video streams). Then bring each seperate file into VMS for editing.

thanx for options.. #3 sounds hairy but i do know that my capture box does give the option of separating the audio and video into their own files..

well, this is interesting.. i found out by playing with the mpg in Pinnacle that the sound is out of sync before any edits are done making me think there's something wrong with the mpg itself maybe in how it was captured. to confirm this, i opened it up again in VMS and saw the same problem - audio out of sync without editing. strange though that the thing plays fine in WMP. don't know what's going on here. as far as i know, this is the only video of all those i captured using same method that has this problem. this would also explain why after converting the mpg to AVI, the same out of sync problem occurs..
could it be something about the original VHS recording that's messed up like what speed it was recorded at (SP,EP,etc)??
