My comp movie/tv show quality is horrible

Hello everyone,

I just built a new system.

I have the Sapphire ATI 4850 installed.
ASUS 19in 1440x900
Gigabyte 790x
4gig ram
Win 7

I beleieve everything says that all dirvers are updated. Except for on my mobo the lan line driver wont update. When I try to up date it stops working and I have to roll the lan line plug back to an older driver for it to work. Dont know if that could be the problem.

When I watch movies or tv shows online the quality is horrible. Looks like everything is faded too brite and online the shows are kinda blocky and choppy.

Although, its usually ok when I have it in a small screen.

Does anyone know what I can do to fix this?

I know its not normal.

Please help me!

Ya, I hear what you are saying.

I was watching 24 off of Fox main site. I would think that site would be able to watch it in full screen?

Any ideas what is wrong?

help, please, it does it in itunes on hd downloaded movies and SD movies. Any ideas??
