Well, I've joined the ranks. Installer was a friendly tech who said he didn't usually do installs, but was drafted into service because of high demand. Installation went smoothly with one exception. Turns out the Motorola remote codes conflict with my Zektor component video switcher. Everytime I'd change the cable channel, the switcher would select a different input! Luckily the switcher can be taught to learn other remote codes, so I have that to look forward to. Until then I've covered the sensor on the switcher.
First HD channel I tried with my Hitachi 57SWX20B TV was INHD. They were playing some horrible movie from the 80's, and I was unimpressed. After the movie, they ran a loop featuring upcoming programs. This video was VERY impressive, especially the nature photography. I next checked out Boomtown on KAREHD. It was widescreen and looked good, but didn' knock my socks off. Finally I flipped on the Tonight Show. Again, I was VERY impressed, and it wasn't just because Pamela Anderson was in HD.
So I was most impressed with the nature photography on INHD and the Tonight Show. The INHD movie and Boomtown left me a bit disappointed. Looking forward to the Vikes in HD Sunday night.
I also got my TiVo and the cable box to play nice together. I ran the SD channels to the TiVo with coax, and ran the component cables to my switcher and into a different input on the TV. I also set my 4:3 override to 480p so that the graphics are suppressed through the TiVo.
