The
For Premiere Elements, I have not found it necessary to convert the video file VOB files to any other format.
When you refer to soundtrack, is this a soundtrack file that you have imported to the Timeline's Soundtrack independent of any audio file that may have come from the VHS tape to DVD (part of the VTS_01_1.VOB and others in that series)?
How are your ripping (copying) these video VOBs from the DVD-VIDEO structure....have you inserted your DVD disc into the DVD burner tray and then opened Premiere Elements and used its Add Media/DVD cameras and computer drive/Video Importer to get the file(s) into the project?
And, you say that you do a lot of editing before you notice the out of sync audio. So, I would ask "If you playback the whole VTS_01_1.VOB in Premiere Elements before any edits, is the audio video in sync?
The answer to all of the above should direct us in developing an appropriate troubleshooting strategy pointing to cause and effect.
Thank you.
