I occasionally have this problem so I burn another disc and it plays fine. The only other option would be redo from scratch. Rip encode and burn. Make sure your sizing is correct so that your using the whole disc.
Wish it were so simple as rebuild/reburn. I've burned 5 discs from 2 DVD source discs with similar results. It's not a case of bad burns, I'm afraid. Further evidence of this is the problems are there if I play the rebuilt DVDs from hard drive. Nor is it a case of bad rips...the DVD9 rips, when viewed off hard drive, don't have any of the problems I see with the DVD5 recodes. I still suspect (but certainly don't know) that bit rates are just too low in the problem areas. But I don't know how to set a bitrate minimum in DVD-RB. Thanks for the get-back.
Bitrate isn't the problem. I have yet to see the final burn on any of my movies with DVDrebuilder have any problems. Any problem along the lines of what your talking about is usually faulty setup, burning software,or hardware. My recomendation at this point is actually buy CCE basic and match what the guide says. It would be easier to figure out the setup problem if you had the same thing as the rest of us and had the latest versions of the programs. Other than a measly $58 for CCE, DVDrebuilder is an inexpensive way to go for the best DVD backup available.
