 I have a Hauppauge HVR-1300 capture card. It has an MPEG encoder (cx88
 blackbird) and I use it to capture analogue signal from my cable box. I
 filled in the channels and EPG with XMLTV and I control the box with IR.
 Everything is fine with V4L capture, but with MPEG capture I end up with
 "I/O error" when I change channels. It seems that the cx88 doesn't like it
 when it's opened multiple times.

 I used Google and my brain, and traced the problem to
 libs/libmythtv/mpegrecorder.cpp. And I fixed it. Patch attached (for
 0.21-fixes). All it does is release the card when the recording is
 finished (i.e. the channel is changed), so it's really simple.

 I'm not sure if 0.22 still has the problem - I'd think it does - but the
 function I changed no longer exists in trunk:
 MpegRecorder::FinishRecording(void), so if you can follow up this patch
 and put it in the right place, that would be wonderful. Thanks.
