Ron,
That is right, if you are NOT a current subscriber, it will cost $64.95+$3.00. Or for current subscribers of all the channels, just +$3.00 for a new box . The 60/75% is what they (Charter) claim to have in HD on their HD channels. This does not include all HBO/SHO channels.
Forget about any local feeds for now, the PR only had a teaser about adding locals later, just like everyone else. This is why I am going to see who takes the next lead in HD, my guess, DISH.
... one thing I forgot to mention, they said on Tuesday they got a notice that deployment of ALL HD boxes are on hold. The rep said it may be because of a compatibility problem with the programmers signal...doh
