Slightly confused

[vage]

Ok so a couple months ago I bought this HDTV:

I really only use it for watching TV and sometimes HD DVDs but rarely. Mostly its for sports in HD and after Christmas it will be for my PS3 also.

I just recently learned that 720p and 1080i are NOT the exact same thing (I thought they were when I purchased this TV). I would like to be able to watch my HD in 720p mode, but my cable box always says 1080i. I've read that some TVs will automatically upconvert to 1080i. I have a Time Warner Cable HD DVR (Explorer version).

Is there a way for me to be able to force the output of the TV to 720p all the time? Will my PS3 run in 1080i or 720p mode? Does the format of the HD Cable have to be set on the cable box or on the TV, and how do I do it either way? I've been looking around for some time now and can't find a decent answer so I was hoping someone could help me out.

Is this your DVR? http://www.scientificatlanta.com/products/consumers/new_explorer8300HD.htm

There's a link to the user manual which describes how to set it up. I don't have a PS3 so I'm not sure what it will do with different content being played.

That is the model I have, the link doesn't help much. There are no instructions on how to force 720p, but there is one thing in there that I need to try still.

I'd still like to hear if anyone has this TV or anything and how it will play PS3 games.
