I just got a Sony 32XBR400 and intend on buying the SAT-HD100. I bought a Toshiba DST-3000 locally with the intention of trying it just to see what I was going to get out of this TV. The Ch. 199 demo & HBO HDTV look awesome. I anticipate the HD100 to look just as well or even better. But my real concern is all other channels look like crap with the Toshiba. Even my DirecTivo looks bad on this TV compared to my non HDTV set. Can anyone with a similar combination tell me what the other non HDTV DTV channels look like with the Sony comboination? Is there any way to get a respectable picture out of the reciever for non HDTV channels. Are there any tweaks or settings to improve the picture. Does anyone know if the newer XBR450 would perform any better. Thanks!
