I have little question about AC3overDVB vs. downmixing in dvd plugin.
Which eats more cpu? I've been so far using dvd plugin and had it downmix
the ac3 sounds. It's working nicely, but I would still like more ac3
sounds. But I'm not sure if my machine is enough for that.. P200MMX, with
64 megs of ram..

Oh, one other question about dvd plugin. Why does it use hd so much? The
hd led flashes all the time and dvd led only occationally. Afair xine did
not use that much hd..
