I’m a bit confused. Is the glitch only when viewing in the timeline? Is the glitch there if you close your software, and play it back with VLC or PowerDVD. And I’m guessing that you are talking about the Womble MPEGDVD software? If so, and your question isn’t answered here, check at www.videohelp.com in the video editing forum. There are some folks there that are pretty good with MPEGDVD.
