Thanks for the feedback gentleman. Clint - I have the Sony Wega KF-50WE620 and as far as I know it does support 1080i or 720p format. Are you aware of something I don't know perhaps? Again, thanks for the help.
I think what they are also getting at is that there is a difference between your native display rez and rez's that are supported. For instance, I think there were some tv's that were naturally 1080p, but could not accept 1080p!!
Only 1080i max for instance.
Hitachi made some plasma that are natively 1080i, I believe.
In any case, whatever your native rez is, if your TV supports 1080i or 720p, you will benefit. Just select the appropriate output in the player. Choose whatever is closest to native display rez, which Clint might presume could very well be 720p.
