No desire to get into a pissing contest, Splicer, so I will drop out of this thread again. Only trying to be helpful. I think we were essentially saying the same thing here and agreeing that the 480p on the player was best.
However, if he is outputting it in 480p, it will be converted to 720p by the TV. Setting 1080i on the input for this channel would be ignored. The input is the max negotiated resolution and would be overridden by the lower resolution being output by the DVD player. Wouldn't hurt anything, and I did set my inputs to 1080i whenever I had a better source available.
You are correct about Feb 2008 being the end for HD-DVD. Not what I was trying to get across, but I didn't express myself clearly in that the Toshiba superior DVD upconversion didn't appear until the A2/A20 in early 2007. I still use my A20 for playing upconverted DVDs. Much better job than my Panasonic BluRay player.
Not sure I agree with your last statement though. Data is encoded on a DVD as a full 480p. You will see a difference between the two when dealing with motion artifacts, i.e. fast moving objects, with 480p giving a clearly better image.
BTW, my 56HM66 is currently sitting idle and looking for a new purpose. The receiver and speakers were integrated into the theater I was finally able to build when we moved into a new house. I also ran and still run an AVR and have an A-20 for HD-DVD, bluRay and even an old laserdisc hooked up. Some stuff on LD simply has never been available elsewhere, so I keep it going. I guess I came back here when I noticed that someone was keeping the old thread active. I was a pretty heavy contributor to this thread a few years ago, but I'm willing to leave it in your capable hands. Sorry for intruding.
Arf, ignore us bickering here. Stick with 480p and component for now, but think of a full HDMI solution in the future when you go BluRay.
