MOst of the shows I am seeing is w/the ratio of 16:9 and I was explained by Tech support that most HD are 16:9 but my problem is that the shows that are not HD are still 16:9 with the bars above and below. And I cant eliminate them. The HD remote has a ratio button but doesnt change anything. I have a 3 year old Sony 36XBR800 and it doesnt have a screen button or zoom. Can anyone help? BTW, I kept my old tivo and both(HD and the old tivo) are hooked up to the TV, and in the old tivo , I get 4:3 ratio. A sidebar question, most channels like CBS next to name it say SAT.and the next channel is Ant. next to the CBS name. I have an antenna in the attic. They(directv) said that I can get HD w/my antenna for local channels. Does that mean that when a CBS show says HD when available, should I be getting HD thru my SAT. (live in LOs Angeles) or does that mean I have to change the channel to Antenna?
