They don't have the bandwidth for the current channels that they have, they are overcompressed and have only been adding SDV channels, which don't work properly. You won't see 50 HD channels, so 500 is a dream.
like CV says "we have the capasity (sp) for 500 channels... but then will we be getting them.. now that a different story...like my bank acct. can hold $500,000 but will it ever?..I think not!!.. but then we don't need all those channels after all CV is giving us caller id on our stbs & we should all be happy!!! LOL
