what he said but interlaced only locks at 30fps and progressive can go 60fps and 30fps but HDMI 1.3 supports a higher fps maybe 120?

the tv has to be capable of supporting 120(120 hz) which sony is releasing or has released some already this year, as will/have a few other companies, 1080i pretty much means you're getting 30/60 frames every second and they alternate every second, meanwhile 1080p gives you 60 frames every second making the picture steadier and less likely to flicker, however the difference is really hard to tell depending on the distance you are sitting from the tv.

1080p is progressive meaning the whole entire image is all assembled at once, resulting in uparalleled looking HD images. It really does look good. The only downside is a TV needs to be 50" and above for you to really tell a difference.
