Myth setup fails to probe my card but everything I have found in my system logs indicates the OS sees the card and it is functioning. I opened a ticket for this but thought I would try to help it along by doing some troubleshooting.

I've CCed the mythtv-users list, since I think you might get more feedback from other users with HVR-1600 cards.
FWIW, I've got a slave backend working with two HVR-1600 cards. I'm only using the digital feature at the moment, but there was a time when I had configured the analog side too. I've got the cards working on a 32 bit system that multi boots the following operating system/mythtv combinations:
mythbuntu 10.10/ mythtv 0.23-fixes
mythbuntu 12.04/ mythtv 0.26-fixes
The 10.10/0.23-fixes combination is my production environment. I'm working on upgrading to 12.04/0.26-fixes, but I'm not there yet. I have recorded a handful of shows with both cards on 0.26-fixes, so I know they work with that version of mythtv and with a 32 bit linux kernel 3.2.
What linux distro are you using and what version of mythtv?
Thanks for the response Helen. I actually posted to mythtv-users first but didn't get any responses that solved my problem. That led me to myth development. I am running Ubuntu 12.04.2 64bit and 0.26 of mythtv. Like I said I believe the OS see the cards. I pasted below some entries from dmesg that seems to indicate all is well. I also read somewhere to run the command 'cat /dev/video0 > test.mpg' and if the file that comes back is a valid video file all is well in the OS. I tried this and the test.mpg was valid.
