Using VS8, I made a DVD with 7 titles and some titles lose sync with video half-way through where i cut ad breaks from editing. When I edit, I have made a habit of splitting audio before saving to limit errors. I nearly always have sync problems and have to be very careful when editing. I always take each section and edit it first, split audio, save and patch together and that usually works but this time I can't fix it.
Any help as to why this is happening would be appreciated.
VOB sync issues

What video format are your original files?
If they are MPEG, that's a fairly common problem. A couple of possible solutons are to capture to AVI/DV format, convert to AVI/DV before editing, or get a special-purpose MPEG editor.

Please understand that if the MPEG is captured with consumer gear, Main Profile @ Main Level, and not HDV it was intended to be a distribution format for VCD/SVCD and DVD, not an editing format. As such editing with it is iffy at best.
Yes, a lot of products support doing this and there are cameras that shoot MPEG direct to DVD, but that doesn't make it a 'best practice'.
You'll get far better results if your hardware permits you to capture in DV or analog compressed with a proven editing codec like MJPeg (I use Morgan-Multimedia's or MainConcept's, both <$20 and with long free trials).
Other options are the free HuffYUV (get ver. 2.20) or the QuickTime 'Component' codec (built into VS and MSPro). Both are lossless, but at 10-12 MB/second create huge files.
If stuck with MPEG sources that need editing my procedure is to convert them to a format that edits better; usually MJPeg set to a high quality setting. MJPeg set this way can be nearly lossless, a big advantage in the edit bay and when you go to encode.
This is called using an 'intermediate codec' and is a common practice when editing lossy sources, especially MPEG.
