For about a year after I got my HR24 hooked up to a (then 40") Sony TV, it sometimes got the display format correct and sometimes showed SD video in HD format, so everyone was too fat. I had to keep adjusting the display settings. I don't know what the technician did, but when I finally reached someone who understood this, he fixed the problem. When I select a channel now, the HR24 seems to pause for a second or so, adjust something internally, so when the program eventually appears, everything is correct. He never explained how he did this, or what he did. I'm curious if someone here can either tell me how this is done, or how I can find all the standard settings, so I can compare them with my settings. It's not important - I'm just curious, and would like to understand this.
