Hopefully one of these days I'll have enough know-how to help out other people myself. Thanks again for the help.
For those of you still tuning in for reports, here's the symptoms:
MythTV shows up on my monitor (I'm VNC'd into the system). All features appear to work fine (the backend is even picking up recordings while I work on this). The checkbox to use the PVR-350 TV-Out is selected, but I still see video through the monitor when I attempt to play it.
Through my TV, however, I am seeing the initial green screen and redraw when the machine is booting. I then see a black screen with a white cursor that starts in the upper left and then moves to the center of the screen. I do not see my MythTV display or anything else beyond that.
Card settings and test results follow:
00:0b.0 Multimedia video controller: Internext Compression Inc iTVC15 MPEG-2
Encoder (rev 01)
Subsystem: Hauppauge computer works Inc. WinTV PVR-350
Flags: bus master, medium devsel, latency 64, IRQ 10

This gives a color test pattern, as expected.

It happens. Heck, I've asked stupider questions. I absolutely relate to the 6 hour thing.
I'm glad it was an easy one.
Sorry I can't offer anything on TV-Out, not having carried the box to my living
room yet. ;)
