real movie 24fps vs. video 24fps

[John Garrad]

I would like someone to explain why even Blue Ray full Hi-def movies labeled as 1920 x 1080 pixels do not look as clear as live full hi-def TV one sees on their cable channel. The difference in resolution can clearly be seen on my 50-inch Panasonic plasma 1920 x 1080 display. I’m sure that it is the video TV camera which shoots at a higher frame rate per second, e.g., 30 fps vs. 24 fps. All of the technical information in this discussion does not seem to answer this question. Thanks.
