WIN7 playing media = network to crawl

[Dimension]

Guys I need help and are starting to pull my hair out over this

I have found that if I am playing any form of media through an app or a web browser my network performance drops to under 1mb/sec. This slow speed continues until I close whichever application is playing the media which sees the transfer jump back to 60mb/sec+

I recall this was an issue with the early release of vista but have never seen this before on Windows 7
This is what I recall having on Vista, but was fixed with SP1

Does anyone else have this on their system, or is it time for a complete rebuild ?

Hmm.. as I was writing this out it noticed the age of the network drivers, I updated to a much newer driver and it appears to have improved the network performance, now I get up to 10mb/sec?

It looks like this build has been running for 3 years as I always use the latest drivers at the time of the build. That's some achievement considering the amount of software that gets installed and removed on this system.

What age is the current driver, dis you get it from realtek themselves?
