PS3 demo problem

I play on a HDTV, but when I download and play demos on my PS3, the demos play in standard def. Is there a way to play demos in HD or do I have to play in SD?

??????? All my demos display in HD, I'm not sure what's happening to yours.

yeah that is very wierd. So your full games play HD but only demos are in SD? Never heard of that before, try calling sony they may have an answer for ya.

There shouldn't be any difference. Try checking the system settings. :)
