OK, if you read my other thread, first you need to buy this:
Broadcom.com - Featured Product - Crystal HD Solution
They can be found on Ebay for roughly $50 + shipping depending on how fast you want it. I can recommend a seller if you need as I bought mine there.
Next, you need this:
CCCP - Combined Community Codec Pack
This will give you the codecs needed to play any media file and the media player that is included, Media Player Classic, works with the HD Decoder and VOILA! HD video on any netbook.
Make sure you open up your netbook and see if there is a PCIE slot before buying anything. You most likely will need to remove the WLAN card to do this, but that is of little consequence considering you'll most likely be near wired internet at home anyways. Great way to turn almost any netbook into a HTPC instead of a paperweight.
