Windows Media Center keeps freezing

In Windows Media Center, whenever I click a video in Internet TV, it just freezes. There are no signs of the video loading. My cursor doesn't change and I can move it around freely. However, I cannot go back, look at other videos or get any response from WMC. I can alt-tab and do anything else with other programs, but when I alt-tab back, WMC gives me a black screen.

If you need any other information about my computer, other than my system specs, just ask. :)

EDIT: It seems like anything that uses the internet (news, music videos?, etc) freezes my WMC. I can play music, pictures and videos fine.

Okay. It seems like it does work. It just takes really long to load the videos. Does anyone know how to fix/improve this or is this normal?

I have the same thing happening to me on a new install of Win7 RTM 64bit with Win7 codecs by shark007 on my laptop. It also did happen when I had Win7RC installed my laptop.

However on my desktop which has Win7RC I do not seem to have a problem.

I also would like to find solution to this problem

Go to Run and type in msconfig
go to the area were it says Boot
Click on the operating system
Click on advanced options
Change your memeory to read 4095. It will default to 4096.
This prevent Win 64 rom load anymore than 3 meg of ram.
There is a bug in Media Center.
It will not run with more that 3 meg of ram.
It work great.

Hope it works
