Dont bother with netflix , some peple may already know about this but youtubeonfire.com is really good , many new films like dumb and dumber 2 , the interview , fury etc in 720p or 1080p , worth a share , this site also works great on ipad (using safari) laptop etc .
apologies if some already know about it , could work on x1 aswel unsure
1080p 720p , some are on 360p sadly but the ones i want to watch like the interview , dumb and dumber and fury are 720p and above , give it a couple weeks though and they will update the 360p films to 720 and 1080 .
in regards to surround sound etc , im not sure lol
