i am getting a good picture now so i see what you're saying...it would be at least as good.
I'm not sure this is necessarily so. A mediocre picture on a small screen can be acceptable. But, when viewed on a large screen, it can look absolutely horrible.
My FIL just bought a large HD rear projection tv hooked to standard def Dish network. I haven't seen it, but my wife said the picture is hideous. Fortunately, he has a rather non-discriminating eye and thinks it looks good.
I just bought a 46" LCD (Sony). I have DirecTV HD DVR. Because this DVR model does not get the local channels in HD, the only hi def programming I recieve is the 5 or 6 HD channels that Directv provides. I cannot receive local channels OTA where I live.
Most non-HD channels still look pretty good at 1080i via HDMI. Some are pretty bad. HD is awesome.
The good news is that DirecTV is coming out with a new HD DVR that will receive my local channels in HD. I'll upgrade as soon as it is available. Also, they are scheduled to offer more in HD channels in the near future.
I see I kind of got off topic a little. Back to the point of my response, don't think that a bigger screen will necessarily give you a better picture (or even as good as the old set, for that matter). It all depends on the quality of the signal you feed the tv. With a standard def input, the old tube-type tv's often look better than the the new larger plasma or lcd HD flat screen models.
