[mythtv-users] Problem with Mythtv & QTE

[Michael Haas]

Hello!
I'm currently trying to use Mythtv with QT embedded on a Matrox G400.
It built fine, and now I'm stuck. My TV is connected to /dev/fb1, so I 
have to setup $QWS_DISPLAY properly. I did, but my TV stays dark. No 
Picture.
When QWS_DISPLAY is set to /dev/fb0, where an old CRT is connected to, I 
get an picture on my CRT. It doesnt look good (8 bit maybe), but hey, I 
can see something ;).
I simply loaded some matroxfb modules into the kernel, linked mplayer 
1.0.pre3try2 against directfb 0.9.20 and got a perfect picture on the tv 
using mplayer -vo dfbmga.
My version of QTE is 3.3.2.

If anyone has any suggestions, please let me know! I'm becoming 
desperate :(.

Here is some debugging information, I don't know if it matters, but it 
won't hurt ;):
