I got it working(kinda)! Ran the fglrxconfig utility setting monitor 1

work for my LCD monitor, so I altered the XF86Config-4 changing AUTO
to CRT in  Option "MonitorLayout", then both screens showed colors and
everything(with scrolling on the TV since the resolution is too high
to fit into the TV).

Haha, dammit, yeah, figured that out, when neither mythtv or mplayer
or anything would show up on my TV, but everything else would...darn,
then it doesn't do much good :(

There isn't anything I can do about the missing xv then?

Do you know if the DVI connection has the xv output in it? Otherwise
I'd be really sad when purchasing a projector and still not being able
to see videos(Well ok, I guess I could get a VGA=>Component adaptor
and use that, but DVI would be preferable..)

It looks almost like that setup, I have two monitor sections, two
device sections and one screen section, here's the essential parts:
