try it if you have one ive been using my netgear bridge for my xbox and never had problems . I admit when I set up my xbox360 to stream media from my media center pc it says hi def may not be reliable however this was with my wireless card on my laptop which ive found not to be reliable as my bridge . How much hi def will you watch from your machine.
the xbox streams as a media center extender so I presume it must be media center edition. Its a clever bit of kit btw. There is also a div x program (havnt tried yet but a friend has) to enable divx streaming.
the 360 will play .ts files and there is a way of making it play divx but I haven't persevered with that yet. Will also stream WMVHD. Blimey, having written that I'm now wondering why I'm considering the snazio lol!
My problem is the connection between my PC and 360 just isn't up to the job. Either need 200mbps homeplug or wired lan (not really practical) or a decent wireless router (of which I believe the new netgear MIMO3 one is the only real option).
