I used a dxr3 for a long time. I am now using a g450. I must say that with directfb & softdevice the g450 does produce a good picture via TV out. The setup is a bit of a pain - I think the documentation should be updated. The one outstanding issue I have is that I cannot view 16:9 material croped/latterboxed onto my 4:3 display without distortions. (This is a known problem, but there is now solution yet) Outside this, I certainly would recommend a matrox over a dxr3 for vdr. > Jon > > > _______________________________________________ > vdr mailing list > vdr@xxxxxxxxxxx > http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
