I use both the Xine frontend as well as the vdr-sxfe (xineliboutput only) for viewing and both work without any problems on my AMD X2 Dualcore system with Geforce 8200 IGP (nVidia binary driver with Xv output).
I'm using vdr-xine-pligin 0.8.2 and xineliboutput (vdr-sxfe). I don't understand why but with vdr-xine I have more CPU load, than with vdr-sxfe with hdtv content. May be someone can explain this moment
