I have an older, 4:3 43" Sony projection TV, (KP-43HT20). I just recently got the H10, and I seem to prefer 480p viewing. This allows the SD programs to fill the 4:3, and the letterbox with HD is tollerable. The higher resolutions seem to leave too much unused real estate due to the large letterbox bars. Am I missing out on a lot of sharpness? My eyes can't seem to tell the difference. The 480p HD stuff looks very sharp, and quite frankly I'm very satisfied with it, I just feel there is something I am missing. Am I the only one who enjoys 480p on a 4:3 TV? Should I be "upping the resoultion"? Thanks for any info you can provide.
