Yes.

Ok.

That's true.

Up to now, I'm using an el-cheapo dxr3 mpeg hardware video decoder, 
which does the decompression and handles the synchronization perfectly, 
of course. The video qualiy via s-video is really good, too.

So I don't want to take a step back...

The only drawback is, that non-mpeg video (ie. avi) has to be transcoded 
on the fly to mpeg, so you cannot integrate this stuff into a pvr with 
little cpu power (Athlon 700MHz is the lower limit is suppose). 
Additionally, using mplayer, sometimes the a/v sync is crap. xine does a 
better job, but fails on some other avis.
