Possibly a little OT but I don't think the 8400gs actually supports hardware purevideo. I have read a few other posts here that suggest the 8400gs *does* support purevideo and would like to get it cleared up in my head. When I bought an XFX PCI-e 8400gs I queried XFX-support on the topic I was referred to:
http://www.nvidia.com/docs/CP/11036/...Comparison.pdf
which does not list the 8400gs as having *any* purevideo compatibility. Strangely, XFX support wouldn't issue a direct answer to my questions (ie: yes or no) and would only state that if it wasn't listed in that PDF then it didn't have hardware purevideo.
Does anyone have definitive information to finally clear this up for me?
