1. FIOS or a fiber based cable Internet provider will be your fastest choices. I don’t have any experience with Sat Internet, but my understanding is that it is slower than DSL with the average download rate being about 1Mbps. Hughes.Net has a 2.0 Mbps/300 Kbps plan for 89 bucks a month, which may or may not be faster then your DSL.
2. Your best bet for boosting cell reception around the house is to get a mini cell site from your cellular provider (I know Verizon, and T-Mobile offer them) they use a little of your internet bandwidth when you are are on the phone. My experience with boosters is that they suck.
3. Rip DVD’s with DVD Decrupter http://www.dvddecrypter.org.uk/ Rip them in ISO format. (Mode/ISO/Read) This will rip them to one big file which you can mount with a virtual DVD drive like Daemon Tools lite. Both programs are free. Once you mount the image with Daemon tools lite you can watch it normally with Windows Media Player or your favorite DVD player.
Of course you will need to hook your computer up your TV if you want to watch them on a TV.
I was at the local home show, they were saying Satellite was about the same speed as DSL. They were talking up Wireless Internet. I learned that for that option, you need a direct line of sight. If trees are in the way, no can do.
