Hmm... I thought snapstream said they'd couldn't get tv-out to work because of fundemental issues with the mpeg decoder or something. One more option is always good :)
As for simultaneous TVout on on the pvr 350 AND M10000, it works. I have the svideo adapter on the mobo, that converts it to composite, and only shows black and white on the TV (a known issue - something about combining the individual signals from svideo cable into the lower-count composite cable). The svideo input on the TV is currently being used by the pvr 350 tv out. I can switch back and forth when I have to. Which isn't often, BTW.
