Video output to TV out on a MGA400DH32MAX

Hi!

I've been reading along for some time but haven't found an answer yet to my 
problem.

Since my system's setup comprises a G400DH MGA card I want to use the TV out 
with mplayer  the way it is done for M$-Win (sorry for mentioning that ;o) 
). Meaning, whenever I run mplayer it should output to the TV solely or in 
parallel to the windowed representation of the movie played back on the 
primary display.

I use SuSE Linux 9.0 which I regularily update using the web based update 
feature. So I have a pretty regular installation with no extra gimmicks. I 
was able to compile mplayer with mga support and managed to create the 
mga_vid driver as well as establishing the mga_vid-device. I ran the 
power-desk thing provided by Matrox and got a new second desktop on the TV. 
But until today I wasn't able to play back a movie in -fs mode on that 
display nor did I see any mplayer window there.

I assume I'm pretty much all set and only a command line arg away from 
'fulfillment' so answering might be easy. Here are my questions: How do I 
have to configure the second display with powerdesk? Do I have to do this 
with that software at all? How do I have to tell mplayer that it should 
address the alternate display (I tried many -vo options: mga, xmga, xv, 
vidix, ... but that didn't accomplish anything)? I tried the latest 
tarball-release and the cvs-sources (both work but for the TV-out).

Does anybody know? Any help, idea or hint to solve that is highly 
appreciated!


Thanks a lot in advance!
