OK, here's some more detail. By the way, I'm trying to get the Mythtv menus on the tv, which is connected to the prv350. Thanks for the help.

1. Run single X-server to the pc monitor and:
- Mythtv plays fine to the pc monitor
- Mythtv plays fine to the prv350 tvout
- Mythtv menus are on the pc monitor

2. Run a single X-server to the pvr350 and all is fine
- Mythtv plays fine to the prv350 tvout
- Mythtv menus are on the pvr350 monitor

3. Run separate servers on pc monitor and pvr350 and get:
- Failure one:
    - get nvidia splash screen on pc monitor
    - get green screen on tv
    - pc freezes and must be hard reset (ctrl-alt-bksp does not work, ssh from another machine does not work, it's froze)

or

- Failure two:
    - both X-servers seem to start
    - get a loud buzz from the TV
    - then tv goes black and buzz goes away
    - then get X-server displays on the tv
    - The X-server on the tv is not right (icons in the wrong place, looks like it might be double or triple displayed).
- If I start mythtv from the X-server on the pc monitor, then play something on the tv, it seems to clear up the X-server on the pvr350.
- When I attempt to exit X, sometimes it exits after a long time (30-40 seconds), but usually it freezes the pc.

So, in summary:
- sometimes it will start, usually it won't
- when it does start, it behaves badly
- it never exits properly
- if it does exit, it won't start again
- and the topper - when it freezes, any file that was recently edited will be completely trashed after the hard reset, unless I had done "sync" before starting X.

Here's part of the xorg.conf file:
