I've having the same problem, random hang when skipping in a dvb
recording. Our signal's pretty good though so I'm not convinced on the
errors in the stream reason. Also worked just fine for years and only
started doing this last Sunday when I updated to svn head again. It does
it a lot when skipping ads now.

Thanks for the patch/hack I'll try it out and see if it helps.
