Ok,

so i'll comment on what i know: the Marvel G400-TV connected to a TV.

Configuring X to use f/b mode with a proper framebuffer mode fixes this.

Keep in mind that i only use a 10years old ~20" TV.

My settings for Live-TV/Default are:
   -resolution 704x576
   -decimation :  2/2
   -mjpeg quality: 70% (no visible difference to 100%)

X resolution set to 640x511 (b/c of the small TV screen)

On the TV, the quality is actually quite good compared to the TV tuner
picture itself. Color settings in mythtv need to be adjusted, though.

Using mythtv on a remote fronted (laptop with TFT screen, ~15" i think)
of course reveals the limited resolution + the picture seems a bit
'noisy'.

Setting the decimation to 1/1 gives a much better picture on the TFT,
but saturates the network (picture pauses every ~ 1-2 sec.).

So if you're not looking for the ultimative Home Theater solution, the
Marvel might still be an option. Ok, the files are huge, but with 100GB HDD
it's not a big problem anymore.

If the PVR 250/350 weren't so expensive, i'd switch to these, though.
