Did you get rid of just the premium digital cable packages, or did you actually revert back to analog cable? Comcast, along with almost every other cable provider, is phasing out analog cable as they can cram a lot more digital channels into the same bandwidth that analog transmissions consume. Sooner rather than later, existing analog customers are going to get a letter mandating the switch to digital cable if they want to continue receiving service.
Also, Comcast has a 250GB cap on residential internet service, so you may want to keep an eye on the usage meter available on their website under your account settings if you're going to be streaming a lot of video. I don't really use Hulu or Netflix streaming, so I'm not sure how much bandwidth they consume, but I've heard that streaming a lot of HD content can cause you to hit the bandwidth cap quickly.
I got rid of the digital package and now use a DTA to get the basic cable (instead of a box). Thanks for the info, many things there I didn't know about. I don't use the streaming services a lot so far, we'll see how that goes.
