    What's the native resolution of the 40" Samsung? Was it 720p or 1080p TV's can scale the signal (1080p coming from a Blu-ray) to display it on a 720p TV. I have a 720p TV and the algorithms it uses to deinterlace & downscale a 1080i signal to my TV has some problems that show up as 'blurred' images on fast motion that has nothing to do with 60/120hz refresh rates. The same motion looks great when it comes from a 720p signal. You won't have any deinterlace problems going from 1080p to 720p since they're both progressive.

whenever i switch the source to HDMI2 (where i have my DirecTV receiver connected) i get a message saying 1920 x 1080i @ 60hz. when i switch it to HDMI1 (where i have my PS3 connected) the message says 1920 x 1080 @ 60hz. all the images through my PS3 (be it a video game or Blu-ray movie) look much crisper than DirecTV (even the HD channels), which leads me to believe my tv's native 1080p.

don't get me wrong; my HD channels look much clearer than anything i ever watched on my old standard-definition, but they still don't look as crisp as stuff through the PS3.

please, keep in mind this is all coming from someone who's far from tech-savy ;\-\)
