vista media center extender running sluggish 360

I have MCE 2005 installed on a dual PIII with 512 RAM, and a GeForce4 Nvidia card w/64mb RAM. the 360 and the mce2k5 run perfect, but recently I have dowloaded the Vista beta and the Media Center Extender runs very sluggish on the 360... ie, UI interface runs very slow. The 360 is connected directly to the Vista PC.
I know that the PC im using doesnt meet the requiremnts for the "real" vista experience, but I know the PC can run the OS. Im also confused to as to why it would be running sluggish since the 360 takes care of the UI graphically using the 360 processing power.
Anyone else experiencing this?

I think its the Vista on that system that is causing the problem, nothing to do with XBOX 360, its using up a lot of resources. -- -- Andre Windows Connected | http://www.windowsconnected.com Extended64 | http://www.extended64.com Blog | http://www.extended64.com/blogs/andre http://spaces.msn.com/members/adacosta
