Anyone else here with an old HDTV?

[Domo-Kun]

I just bought a cheap ass 34 inch HDTV. Little did I know, this particular TV does not support 720p. This isn't a huge deal since most HD television and Blu-Ray movies will play in 1080i. However, the PS3 games that run 720p max native resolution all get scaled DOWN to 480p. This sucks pretty bad.

I'm a little annoyed at Sony for not adressing this issue, as XBOX 360 will automatically upscale all content from 720p to 1080i.

 

Does anyone here know of any way to force the PS3 to upscale? I've heard of upscaling boxes, but the only ones I can find upscale 480 to 720 or 1080, not 720 to 1080.
