Good. I'm assuming your audio issues are resolved.
I was able to run tests 1-3 with Composite as the alternate input (I
need to dig up an S-Video cable), and test 4 with PAL as output by a
PVR-350 into the HVR-1600's composite. Things were all OK - so I don't
think I broke anything.
Daniel provided positive feedback on the ivtv-devel list as well. I'll
probably ask this to get pulled to the main v4l-dvb repo soon.
