Choosing 720p or 1280x720

[Canuck73]

XBMC gives me the option of choosing either 720p or 1280x720 for my DLP.

Both are the same, so am I correct in assuming it does not matter which one I choose? Or is XBMC "picky" and the 720p needs to be selected for SD upscaling?

Just thought I'd throw the question out there.

720p is a legacy xbox resolution, you should be using the 1280x720 one, though I don't think it currently makes a difference
