Re: HVR-1800 Analog Driver: MPEG video broken
I just tried again with a live CD running kernel 3.2 and got clean video with cat /dev/video1 /tmp/foo.mpg. So there is a definitely a regression here. Please let me know what I can do to help track it down.

So there is a definitely a regression here. Please let me know what I can do to help track it down. I'm already about 95% certain this was something introduced in Steven's last batch of cx23885 changes for the HVR-1850. I just need to do a register dump for both the working and failing case, see which register got screwed up on the 1800, then look at the code figure out how it got into that state.
