Judder using Mplayer... maybe force different resolution/refresh rate?

Hi!

I've set up my computer as a media center using Freevo. As the main media player in Freevo I use Mplayer. The setup is working beautifully, but I'm getting some judder and it's a bit annoying. It's most noticable during bright, fast moving scenes.

So I've been trying to figure out how to remedy this, but it's harder than I thought. My setup is the following:

AMD 4200+ dual core, 2 gigs ram, Nvidia 7800GTX, 24" LCD and Pioneer LX508D plasma TV, and I'm using CoreAVC as decoder (amazing piece of software )

When I bought the 24" screen for my computer the sales guy (using windows) forced the resolution to 1920x1080. It looked a bit stretched, but if I could do this in Linux I'd avoid having parts of the picture missing on my TV. Now I have to use 1920x1200 resolution as main X session and since my TV is 1920x1080 parts of the desktop is out of view on my TV. This isn't too big of a deal though cause when playing movies they come out in 1920x1080. It'd be nice though to get the correct aspect ratio between my pc screen and my TV (I've been trying to use Twinview and clone, but it's impossible to use 1920x1200 on the 24" and 1920x1080 on the TV at the same time). I've tried to force my pc screen to use 1920x1080 (since it worked in windows it's supposed to be possible), but when I enable it through xorg.conf the screen goes blank. Using nvidia-settings doesn't give me the option of using 1920x1080 on the 24" at all.

So what I'm hoping to be able to do is to force the computer screen to use 1920x1080 and a refresh rate of 72Hz. This should eliminate alot of the judder and at the same time I won't have to use the "PC mode" on my TV (PC mode restrict the Hz to max 60Hz). Hopefully the TV will accept the 1920x1080 72Hz as any input and let me use the normal input (and then be able to use 72Hz... or 96Hz for that matter).

Anyone know how I might be able to do that? I'd really appreciate any help at all since this is the only thing that's not perfect with my setup.
