I received a call from Cox today telling me that as of Sept 10 I will receive no new HD channels because I use CableCARDs and offering to rent me a Cox set-top box. I asked if this meant Cox was going to use SDV, but neither the representative or her manager knew what that meant. Checking my most recent bill, I found this on page 2. "In order to enhance our services and add new channels, Cox has beun a process called switched digital. Current CableCARD customers, whose host devices do not offer two-way communication capabilities, will not be able to access 54 of the switched digital channels (mostly pay-per-view) starting September 10. Unfortunately, Cox has no control over the technology in these host devices. We can offer you the option of leasing a Cox digital receiver so that you can continue to have access to all of the programming we have to offer, plus On DEMAND." I called Cox back and spent half an hour on hold while they tried to find out what 54 channels will be SDV, only to be told that that information had not yet been released. I did a quick search of the forum, but I didn't see another announcement of Cox implementing SDV, only TW and Brighthouse, so I thought this was worth posting.
