Most of the content is still SD, and I am a real pedant about smooth video / interlaced output for scrolling text / live sports. Any time that I've played with vdr-xine or xineliboutput over my years with VDR, it's always been a bit juddery due to VGA timing not matching up with the TV.. is that improved any in the world of HD / HDMI?
Take a look at these patches:

I believe they are useful also for HDMI/HD stuff. I haven't tried them yet myself.
