Audio streaming stops after about 13 minutes.

Question

Audio streaming over the Internet just stops after about 13 minutes and has to be restarted. I need a solution

Answer 1

Thanks for your help! You helped solve the issue, albeit indirectly...
At this point, I want to share my experience, in the hope that it might be helpful to others:
After finding that chapter markers had nothing to do with the problem, I found that indeed my camcorder was set to the dreaded 12 bit. Oh dear! The original DV tape is long gone. (At first I did not expect this to be a problem, since I had made several DVDs successfully with the existing settings, but then there are all these horror stories in discussions about what 12 bit can do to you.)
So to rescue my movie, I found advice to "share" my iMovie back to a fresh DV tape, and then re-import it with the 16 bit setting.
This lead to the next issue: After a number of minutes of re-exporting to DV tape, the video received by the camcorder would freeze, while the audio continued. This happened at several different points in several differerent attempts.
So next I visited iMovie discussions, where I found advice to clean up my Mac. I used Mac Sweeper, and now indeed my Mac runs faster and smoother for many apps. I also downgraded my QuickTime version. But another attempt of exporting from iMovie to DV tape also failed, but now it failed at exactly the same point where the audio stopped in my DVD!!! (Even though on the export-to-DV-tape it was not the audio but the video that froze.)
Next I found that when playing that problematic scene in iMovie, the iMovie program would also freeze at that very point, making it necessary to "force quit" out.
In the end the solution was to chop out the problematic bit in that scene. Now everything works fine, including the iDVD step.
