[mythtv] Realtime Commercial Flag / skip problem

I'm having a similar problem with the latest cvs build and commercial
flagging. I've been trying to track the problem down for the last
week, but it's really confusing me. Real time commercial flagging
works for HDTV programming using a dvb card. Real time commercial
flagging for regular tv programming using a bttv card recording a
RTJpeg stream does not work. I usually get an error message on the
backend about waiting for data to become available, and then it
repeats the message 5 times or so and then says the data has not
become available after 10 seconds, aborting. But, if I go back in
after the recording is done and manually schedule the commercial
flagging job, it works just fine. What really confuses me is why the
real time commercial flagging works for the hdtv programming but not
regular programming. Any ideas?
