Will I still get the same Comcast basic cable channels, after the digital switch? I have an unusual tv setup?

There is no need to worry about losing anything. Remember that the cable company, regardless of how they get their signal, it has to be sent over the cable in analog form for all the people that don't get digital cable. That's why they keep saying, 'don't worry'. BUT that doesn't mean that they won't cut analog at a later date and make you go digital. Now, that sounds scary, but it isn't. They will supply you with whatever boxes you need for your old TVs to keep them going. So you might ask why will they go digital down the road? Because they are hogging bandwidth shooting digital signals down their cables for digital and HD subscribers, and sharing that space with you the analog users. They are transmitting the same thing TWICE, and for obvious reasons, they can't do this forever. Yes there could be a channel change around, but there is no technical reason for such a thing in Feb when the change happens. The switch is only for over the air transmissions. only people using a antenna are going to be hit on day one. You getting the same channels, or seeing some change is really going to be your cable company's doing, it won't be related to the switch, make sense? The required box could be true for additional programming because that's the case right now with my cable. Bottom line, relax, you are their customer and their money tree, they aren't going to cut you down. Even if they switch to all digital at a later date, they'll supply you boxes, and the benefit of not transmitting both analog and digital will be more channels for everyone.

The commercials are kind of deceptive... The government is forcing ALL signal to be changed to digital. Broadcast signal from TV stations is obviously switching to digital. Satellite is already 100% digital (that's kind of intuitive, it involves sending a signal to a satellite and beaming it back down to Earth...) However, because cable companies are big, slow, and stupid, the government has given them extra time to switch over to digital (6 months, a year, I'm not sure how long.) When that happens, the cable company will provide you with whatever you need to keep your service running. Since they're a cable company and enjoy ripping you off, they might charge you for it, but who knows. Point being, don't buy a conversion box for cable, because it won't work.
