What is the difference between Xen domain dom0 and domU (for a Xen newb like me)? > I can tune to channels and I get data when I cat /dev/video0 ... but > the data doesn't seem to be valid video. You may wan to try using v4l2-ctl to enumerate the controls (with menu options) and then changes the card to generate an MPEG2 TS instead of the default MPEG2 PS. A TS is more robust to small amounts of data loss than a PS, so maybe things will be a little better. > Does anybody have input on how I can work towards a resolution on > this? Note the CX23418 is very latency sensitive. If the guest responds too slowly to CX23418 interrupts, it will miss the CX23418 mailbox payload data and hence lose video buffer data. The CX23418 won't wait forever for the OS driver and will move on. (This is a firmware bug IMO, but likely considered a required feature if you ask Conexant).
