Maybe some day FrameRateControl will allow for a pure open source HDTV solution. Running with adequate picture quality on moderately powered CPUs.
Yes, hopefully one day Intel will have a fully operational VA or something, including MPEG 4, and include HDMI or DVI on the motherboard instead of having an adaptor taking up a valuable PCI-e slot.
I wouldn't consider FrameRateControl absolutely vital, playback of live TV is smooth enough without it IME, but ironically libxine seems better at playing live TV than VDR recordings which always seem to me to suffer more frame jumps, loss of AV sync and pops in the sound than live TV.
When playing back recordings it doesn't matter if the video output frame rate isn't quite right, you can avoid dropping or repeating frames by resampling the audio if sync starts to drift - this appears to be an option in xine's config, but it doesn't seem to work correctly on recordings for me.
I already sometimes use resampling in mplayer to watch 24fps videos smoothly at 25fps and the sound quality is still subjectively OK - certainly less intrusive in the overall "experience" than jumping video frames.
