Earlier this month I upgraded from an HR24 to an HR34 setup (got a killer NFLST renewal to go with it). In my living room, I have the HR34 connected via HDMI to a Denon 789 which connects via HDMI to a Vizio 55" TV. For 2 years, I had no issues with an HR24 and this setup. With the HR34, any time I switch from a 1080i to 720p station (or vice versa), the HDMI connection loses sync and requires me to power cycle the TV. It is extremely annoying and will likely induce eye-bleeding rage once I get to football season and NFLST. I haven't tried to fix the resolution to 1080i to see if that resolves the issue...but I shouldn't have to. Anyone have or are aware of a similar issue?
