Would be interested if you see any difference when changing modes. When I do it the size of the guide changes and I can notice it.
When you say changing modes, are you referring to the HDTV set-up menu in the 811? If so, I tried this awhile ago & I noticed I saw no difference between 1080i & 720P, neither in the PQ nor did the EPG look any different. (I thought this was a little unusual). However when I changed over to 480p in the 811's set-up menu, the EPG became huge. I cannot say I saw any noticeable difference in PQ.
