Working for the 3rd largest cable co in America I understand about the differences in digital vs analog. Personally as far as bandwidth is concerned 6 digital channels fit into the space of where 2 analog channels sit.And you are right...with analog it is more robust,,,,customers can hack there cable lines with a shovel and practically cut it in half and they still will have a picture,,,crappy but a picture...whereas if our digital is not setup correctly it will freeze frames or totally go out....we prefer the digital becaue of the quality of picture and the amout of info is greater as far a a tv pic is concerned anyways...
On the note of music I hear what you are saying...I have been told by musicians that Vinyl sounds way better than digital music cd or tape whatever.
How stuff works....good topic.
