It looks like Time Warner Albany is starting to switch channels over to SDV. Today we lost Nickelodeon and I don't know what else. When you switch to Nickelodeon on a TWC box it has "To start over press SEL" so it looks like they are adding some "features" I don't care about (and am surprised to see when I don't have a DVR sub or a DVR box) to the signal. I'm assuming this means it's using SDV or some proprietary something. EDIT: It looks like they've been offering the "Start Over" service for a while and I've just never seen it. It's only offered on certain shows, but it looks like it's expanding. When "Start Over" is enabled on a show, you can't access the channel. See http://www.timewarnercable.com/Albany/Products/Cable/start_over/channels.html for a list of channels enabled for "Start Over" at TWC Albany.
