I'm a relatively new Mac owner and I've just started trying to burn movies to DVD, and I'm running into the same problem every time. I burn the movie, and start watching it on the DVD player and the quality is great and the sound quality is great, but about 10-15 minutes in, the sound cuts out. If I play back the copy that's on my hard drive, there's no issue with the sound.

What am I doing wrong? Could it be the quality or capacity of the DVDs I bought? I'm using 120 minute Fujifilm DVD-R's (4.7 GB and 16x). Aforementioned problem occurs when I burn the movie using iDVD. I tried using Toast Titanium, and while the problem didn't occur, the picture quality was horrible.

Any advice would be greatly appreciated.
