It will totally depend on the type of display that your using. Upscaling is a process that mathematically matches the pixel count of the output of the DVD signal to the physical pixel count on an HDTV, which is typically 1280x720(720p) or 1920x1080 (1080i). Visually, there is very little difference to the eye of the average consumer between 720p and 1080i. However, 720p can deliver a slightly smoother-looking image, due to the fact that lines and pixels are displayed in a consecutive pattern, rather than in an alternate pattern. The upscaling process does a good job of matching the upscaled pixel output of a DVD player to the native pixel display resolution of an HDTV capable television, resulting in better detail and color consistency. However, upscaling, as it is currently implemented, cannot convert standard DVD images into true high-definition images. In fact, although upscaling works well with fixed pixel displays, such as Plasma and LCD televisions, results are not always consistent on CRT-based high definition televisions. hope this explains it.
So the video upscaling only affects DVD playback and not the satelite receiver input signal. Is the difference in the picture quality of Dish Networks HD programming worth the expense of upgrading? I have a 52" RCA CRT based with an integral HDTV tuner and was thinking of upgrading but am not sure if it's worth $199.99 for a receiver and $20 more each month for programming.
mth57 might be referring to the component upconversion feature found on many of today's home theater receiver. If this is the case, users can plug composite and S-video sources into the receiver, and the receiver will convert them into component signals for convenience. This prevents the user from having to constantly swith inputs on the TV when viewing analog sources.
If it truly does have a video upscaling feature (there are receivers that can do this), I wouldn't expect any major changes in video quality. Besides, if it is a digtal display, it will already have some kind of processing that does this, then it's a matter of determining which does it better.
Is there a noticeable difference between Dish HD and the regular digital picture? I have an RCA HDTV with an integrated HD tuner. I am assuming that I am watching a digital quality picture with this tv and was wondering if it was worth the expense to upgrade to HD.

Only if you have an HD capable Display. If you get an Hd brodcast, your not going to notice the differance in picture quality.
