I'm having big problems with my audio syncing, I record an MPEG2 from the TV trough my AVerMedia DVB-T USB2.0 then use DVD-lab PRO to author it. The audio is in sync on the original file but seems to loose it after authoring. the sync seems to get worse as you go later in the movie. I scanned one of the original mpeg2 files with PVAStrumento 2 and I got loads of errors (below) Found 1 video stream. Found 1 MPEG audio stream.

Well if you Run your Files through PVAStrumento it should Fix those errors and resync it so the DVD Plays Properly and in Sync .... Digital TV and Satalite Streams can Be Difficult to make DVD"s from because they have an Inconsistant Time Code because of Signal Drop out when Captureing...PVAStrumento is supposed to fix this but even then you can still have Problems.... To Fix the GOP you can Try useing a Feature in a Mpeg editor called "Womble Mpeg2VCR" which is called the "GOP Fixer" which will fix any Non-DVD Compliant GOP"s in the Video stream.... Well Good Luck.......
