[mythtv-users] Can't get video on both projector and TV at the same time.

Wed May 4 18:55:27 UTC 2005

Hi,

I've been struggling with getting mythtv to work with both a Projector and a
TV.

The problem i have is while i'm looking at live tv or at a recorded show.
The problem is that I either get the video on the TV set or on the
projector. I've never been able to output the video to both the projector
and the TV at the same time. The MythTV GUI is though present on both
screens (as well as normal KDE operations).
The reason for why i need this to be solved is that i sometimes use the TV
to look at programs and sometimes i use the projector and it's not an option
to reconfigure X between these times.

I'm using an ATI Radeon 9600 and the TV is connected using S-Video.

If i use 
  Option "OverlayOnCRTC2" "on" 
then the video is on the TV
If i remove this line, the video is on the projector.

Below is my XF86Config-4 file and i'm running Debian Sarge, Myth 017,
Xfree86 v4.3

Is there any way to get the ATI card to put the video on both my TV and
projector?
If not, would i solve my problem in ´buying an Nvidia FX5200 card instead?
Or is the only solution to use an external vga-tv adapter instead?

Thanks in advance
