Thank you for the reply. It seemed to me that my system would be able to
decode MPEG2 at a decent resolution because I can watch my ripped DVDs with
mplayer using just over half the CPU. This seems to confirm the theory.
I don't recall the default setting either, but I think it's something like
I wonder if scaling has anything to do with the performance? The TV is 4:3
and your output is 800x600. Perhaps you could get better quality by using,
say, 560x420, which is about the same number of pixels.
A lot of people are afraid of heights. Not me. I'm afraid of widths.
