2.0GHz is not quite there to play 1080i, as far as I know. People
were saying you'll need at least 2.4GHz, and to get some breathing
room you probably want to go 3.0GHz. I used to play 1080i on my
desktop with 2.4GHz and I'll have to close other applications. Now I
use 3.0GHz in my Pundit-R box.

I don't think so. It may be a problem of the hardware, the driver, or
the Xvideo, or the combination of them. I connect it to a 1024x768
HDTV monitor, I also tried to connect it to my 1600x1200 LCD monitor.
The pink bar is always there if I use Xv output. I can only avoid
this problem with Xshm output, (-vo x11 in mplayer, NO_XV for Myth).

I would like to hear more about this.

But I don't think the bottleneck is there. And what do you mean by
mpeg2 acceleration? Hardware decoding of mpeg2? I don't think
IGP9100 has this ability.
