hummm ... this sounds like the new architecture looses some performance on
low-end machines ... I think we'll need some fine-tuning here.

It'd be interesting to know if these drop rates get better with time since
the 0.4.x series doesn't do pre-buffering yet (BTW: there is no xine
4.0.1 ;)). BTW: are these skipped or discarded frames?

Anyway, there's still hope: the new libmpeg2 looks faster to me, we'll
have pre-buffering again soon, and there are quite a few "magic numbers"
in the code to do some fine-tuning.
