Video playback on a netbook
lapa321:
AWESOME! At first it didn't work and the video wouldn't move past the first frame, so i tried downloading new drivers and the now they all stay under 10%!
Thanks! I'm gonna do this when i get the U230!

Search up a bit about the Radeon HD 3200 just in case. I have no idea whether it will have the same video decoding capabilities/compatibility as your Radeon 5850. They are generations apart.
The Radeon 5850 is UVD2 and the 3200 is UVD. http://en.wikipedia.org/wiki/Unified_Video_Decoder *cough* wikipedia *cough*
Lots of bits and pieces about the hardware in the comments here: http://imouto.my/watching-h264-videos-using-dxva/

You 100% sure, i know that using CoreAVC give lower quality output.
If DXVA dont lower quality i will try that on my 8800gt

Depends what component is doing conversion to RGB. CoreAVC's YV12 output seems to be pixel identical.

Not true. The h264 spec requires the output of all decoders to be identical. Even the deblocking (this is where the quality in different mpeg-4 asp decoders lay in the past) are exactly the same now. There where some bugs in coreavc back in 2007 that could in some cases produce worse output but those are long gone.
