Video Streaming

Recently I started having a lot of trouble streaming video in WMP while using WB. The video is very, very jerky and stutters almost constantly (not making fun of it )

I have tried excluding WMP but I still have the same problem. As long as WB is unloaded the videos stream and play fine. This is something recent as I have not had any problems with this in the past.

One of the sites that I stram from is gametrailers.com

Also this only happens with WMP not quicktime or flash.

Using Vista Ultimate

Any suggestions would be appreciated.
