I gave that a shot and got the same result. There's only a black screen and no sound. When I go back into MythTV setup and deselect 'User PVR350 Out' then I am able to get a picture with sound, but since it is only a 1.2 Ghz machine it is a bit choppy at times.
Wait -- if you're already running off PVR 350's framebuffer, I'm not sure that you can also use its MPEG decoder, at the same time. I think that the 350's MPEG decoder can only be used if you're not using its framebuffer, and you're running X on your native VGA monitor. Myth's menus would still appear on your monitor, but playback would go through 350's TV-Out port.
I have Myth running on an ancient dual Celeron 500Mhz machine, 256MB RAM. Plenty of power to record and playback video, on PVR 350's framebuffer.
You're likely running a consumer-level IDE hard drive. ATA IDE generally demands more CPU than SCSI, and with video record-playback being so I/O intensive, your choppiness is fairly likely due to the CPU getting pegged for I/O. 1.2 Ghz is probably not enough to handle encoding and decoding, and IDE I/O, at the same time.
