Reading various posts has left me somewhat doubtful about my method to obtain the highest quality picture. I have one 1080p TV and one 720p TV with an HR10 hooked to each of them. I set the 1080p to 1080i on one HR10 and set the other one to 720p. I seem to get a high quality picture on both, but now I am beginning to wonder if I am missing out on an even better HD experience--- especially when I read some of these posts. Please advise .
