[mythtv-users] Firewire Capture Working - Playback Gives Bluescreen

Hi,

I finally got firewire capture working from my SA3250HD cable box, but I can't play it back.
I can see the video in the preview window,  so I know I captured something.  But,  when I try
to play it,  I get the audio, but my screen is solid blue.

O haven't upgraded to the latest Mythtv version yet.  I'm so close on the firewire capture, that I
did not want to risk a set back.

A little about my frontend.  Motherboard based on the Intel 845G chipset.  I'm using the built-in VGA output.
I'm connecting to a Mitsubishi WD62725 DLP  TV which has a native resolution of 1280 x 720.

I think I'm using the Intel i915 drivers, but am not positive.  In xorg.conf,  I have "Device  intel".  lsmod
shows the i915 drivers loaded.  No i810 and the only driver that say intel are sound card related.
But,  if I change the Device to i915, and restart X, it fails claiming it could not find the drivers.

After doing a lot of reading of these forums and the Wiki,  I came up with the following modeline:

    ModeLine "1208x675" 74.250 1208 1336 1384 1648 675 702 707 750 +hsync +vsync

mythfrontend -v playback gives a lot of output.  This is what I think is the most relevant:
