I just wanted to add my 2 cents in here with my experience with the HD-PVR.
I've been trying to get this working for about 4 weeks (not solid, I have
been using the firewire successfully in the interim). I had a fairly recent
firmware installed out of the box (0x0f), but try as I might using the
information in the HD-PVR wiki, the backend would fail on all recording
attempts. I started over by upgrading the firmware at Hauppaugue web site.
It now sits at 0x12. After re-adding the HD-PVR to the backend, I actually
got a recording to be made with no errors in the log file; however, the
recording itself was unwatchable. The recording would "stutter"; it would
play fine for 2-5 seconds then stop as if it had been paused on a single
frame for 1-2 seconds and then repeat. After searching the recent posts and
finding your post, I decided to go back and change the output of my DCH3200
to 720p (it was at 1080). I had left it at 1080 because, as you pointed
out, the wiki said this step should no longer be required. I am here to say
that when I changed to 720, not only did I get no errors while recording,
but the playback was flawless. So I would say, at least in my case, 720p
output is required.
