I get the same audio/video sync problems, on recordings too. but it will
happen predictably after advertisements was cut out, it will start to go out
of sync by the first cut. I also noticed that my cpu usage increased and my
system's clock seems to drift into the future.

unfortunately I cannot upload a sample, since my service provider has set a
limit to my upload speed and causes time outs :(
Klaus mentioned that he can only help, if I try without any patches.
