I’ve noticed a peculiar thing when I watch pay-per-view or free-on-demand movies from my cable provider. Especially with the free ones, I notice that I sometimes have problems getting a good clear presentation on my TV. The program will be jerky and occasionally pixellate into green rectangles of various sizes. It doesn’t do this over the whole screen, but just here and there. Still, it’s basically unwatchable. So when this hpapens, my SOP is to power down the cable box and turn it back on, and try the movie again. This usually fixes the problem, although sometimes it takes two or three tries to get it to work.
If I’m interrupted and have to resume watching the movie later, their system will remember where I was and start the movie at the appropriate point, but sometimes I have to go through the same routine as described above to get a good picture
Is there any procedure that will guarantee a good picture from the outset? And arising from that, how do pay-per-view movies work? How does the software and hardware involved deliver the movie to the person who ordered it, and enable the viewer to pause, rewind, fast forward, and play it?
