Just curious to know why if the cable card is authorized to a user why it will stop working when unseated or removed and installed in a new TV set?
It doesn't stop working when removed, it stops working when you attempt to plug it into a new display or device. If authorized CableCards would work in any TV, there'd be nothing stopping you from giving one to your neighbor down the street. Hence, CableCards are mated to the original device where they are installed.
Most cable companies are doing this, or soon will be, and Comcast is not alone by any means. Older versions of Motorola and SA head-end software did not support this, which is why Comcast and some other cable companies weren't able to do it in the past, even though it was their plan / intention all along. Now that the software is available to them, they are taking advantage of it to curb piracy.
I've seen other people on this forum mention installing their own authorized card themselves............What's up with ComCast?
Only the cable company can authorize cards. In some areas, cable companies will let you perform the initial CableCard installation -- basically, they give you the card, you stick it in the TV, and call a 1-800 number to activate. However, after that is done, the card is typically mated to that TV, and will de-authorize if plugged into another device.
I also called Sammy a while back and talked with someone about the TV Guide NOT working. He said it's lack of collaboration with Gemstar and cable companies, or something like that?
Current CableCard technology is unidirectional, meaning your CableCard device receives data, but it can't send a request for guide data. Since your TV can't request guide data from Comcast, it has to get it somewhere else. For its CableCard DVR, Tivo gets its guide data using the Internet (i.e. wireless).
Most TVs with integrated CableCard use the TVGuideOS software from Gemstar, which pays broadcast stations like PBS money to deliver their guide data in the blanking interval of the television signal. Unfortunately, this free service is not available inmany areas. In some markets, the broadcasters want more money than Gemstar is willing to pay for the datacast; in others, Gemstar simply doesn't feel the market is large enough to justify the effort / expenditure.
Currently, the only way to get guide information from Comcast
is by using their set-top box or DVR. Most Comcast customers on this forum choose to get the HDTV DVR, since it is only $9.95/mo, pretty cheap considering it is a $600 box.
