I've just ordered a 27" RCA LCD TV, model LCDX2722W, which has a 1280 x 720 resolution panel . When reviewing the features it says:

"The advanced de-interlacer progressively converts incoming signals and up converts to 720 progressive line panel with 25ms response time."

Is this a good thing? Will it potentially improve on digital cable TV signals? How about old VCR tapes?

Thanks.

It's merely converting everything it's fed to the native panel resolution. How good it looks depends on the quality of the source material, and the quality of the video processing in the set.

With a 1280 x 720 display panel the TV must convert incoming ordinary broadcasts to 720p progressive otherwise the picture would be small (occupy 480 rows of pixels) with black borders on all four sides.

The 25 ms refers to the time it takes to change the picture content from one frame to the next. This is more than 1/60'th of a second and some viewers may notice a slight smearing (comet trails on small bright spots) during fast motion of non-film video. CRT technology is not completely immune from this either since it takes time for the phosphors to decay back to dark.
