Do any BR players exist that have a HDMI input? I think it would be benefical to to be able to hook a cable box feed via HDMI into the BR player and utilize it's video processing capabilities. Provided of course the BR player has a good video processor. Kinda like having a DVDo Edge with a BR player.
No, no Blu-Ray players have HDMI inputs. The only Blu-Ray player with a scaler that good would be the Oppo BDP-83, with the same ABT 2010 scaler that the DVDO Edge uses. If you want a scaler, you'd probably do better to actually get one; Blu-Ray players probably won't have any reason to include this sort of functionality, ever.
