Does fxtv run (with rgb)? FXTV runs just fine, for short periods of time (I don't have an X display on the amd64 box, so I run fxtv over the network to a different box's X display. Not the fastest :-)). However, I don't know that FXTV runs in RGB vs YUV mode... I'd have to look at the code. Anyway, it works, I'm happy :-) Cheers, -RK -- Robert Krten, PARSE Software Devices Join us at BSDCan 2006, see www.bsdcan.org Looking for Digital Equipment Corp. PDP-1 through PDP-15 minicomputers!
