Snipping is appreciated, but ya took out a bit too much there... What don't I 
believe is possible? Had to look back at another email to figure that out. 
Just wanted to point this out. :-)

Yes, its technically possible to display the same thing on both the 350's 
output and a nVidia card. However, they're VERY different output devices. I 
don't think you could do mirrored mode, because anything OpenGL would attempt 
to render on both heads and choke to death trying to render on the 350. If 
you have seperate heads, you have to tell Myth which one to run on, which 
can't be done on a per-module basis. I *have* heard of someone who ran pretty 
much everything on his video card, but enabled "use PVR-350 output" for 
playback. He'd select a recording in the UI while viewing through the video 
card, then flip to the PVR-350 for video. Not the most elegant solution, but 
probably the closest to being able to do what the OP is after right now.
