no cable is different, that's why it's good/worse, lol...
just how the tech is, analog and all
satellite being digital and to save bandwidth, you tune into a channel individually...so the tuner grabs a station and that's it
cable, it's basically all the stations/channels are fed to you simultaneously.
That's why you could have the cable guy come to your house and just install one wall jack. Then you could buy 50 splitters and pip them to 50 tvs and each surf with whatever they want.
Satellite...1 channel per tuner
so basically you can pay them what $5 for each additional channel you want to view alternately...sucks right?
edit: of course, might be different with digital cable, but I believe the physical cable delivery is why the bandwidth is capable of delivering more than one feed vs satellite
