Hi....WHS has a 4GB limitations?

I had 4GB in my WHS box, but had to take 2GB out to stay below 3GB otherwise the Hauppage drivers for the MCE150 dual capture card don't work....

Any problems with the Happauge HVR 2250 and 4GB of ram? I need HD capture anyway and want my other 2 GB in...so i'll probably just sell the MCE150 and put the HVR 2250 in.

Can you capture HD for most of the local channels MSNBC, FOX, etc without any trouble?

The Happauge HVR 2250 can do 2 HD streams at the same time right?
