Re: Lots of issues

OK, I'm in Australia where things are a bit different but I've got a Loewe high def LCD TV and both my separate free to air digital tuner and my DVD player offer rescaling from standard def PAL (576i) to 720p and 1080i. My TV has a native resolution of 1366 x 768 so if I allow my source to upscale things to 720p The TV is still going to have to do another rescale from 720 to 768 anyway before it can display the picture.
What I found was that I'm better going with straight standard def output from both the tuner and the DVD and letting the TV do all of the scaling in a single hit. I definitely get better results with only 1 scaling operation than I do when some scaling occurs in the source component and some in the TV.
I think it would be a much more interesting comparison if my sources could rescale to the TVs standard definition of 1366 x 768 so there was only one rescaling operation and the choice became whether to do that at source or at display. Then the question would depend simply on which device did the best rescaling.
Since your TV is 1080i and your cable box can output 1080i, that's the position you're in. The answer is simply going to depend on which of the 2 can do the best conversion from 480i to 1080i. The only answer that makes sense is to try it both ways and see which you prefer.
