Hi, I have a home theatre set up that ive listed below. my TV is currently playing games at 1080i, but was wondering if i got an xbox 360 HDMI cable (about $50 au), would they run at 1080p? i asked a dude in EB games and he said tv's under 40" dont have 1080p, so the HDMI cable would have no effect. but if thats the case why does my TV have a HDMI slot on the back? also would the cable make my surround sound better? i currently upmix stereo with pro logic as im picking up the amp tomorrow, intending to get digital surround sound - do i need the HDMI cable for that as well? oh and also would the HDMI cable play my HD DVD's in 1080p instead of 1080i, or like the xbox itself, it wont play in 1080p because the tv's under 40"? ive put pics of the back of the systems so you guys can see the connections needed (see attachments). 1) an xbox 360 2) an xbox 360 HD DVD player add on 2) a Digicrystal 26" LCD HDTV 3) a Sturm 5.1 surround + sub 4) a Luxman 2800 7.1 digi sound reciever any help or clarification on the matter would be really, really appreciated! thanks heaps!
