Hi Def digital cable

[rverdlm]

I posted this on the MS section, but this is probably a better place;

We are on the road again and we're finding more and more of the CG cable systems are hi def digital. Our '05 Sharp Aquis won't recieve these channels. It will recieve digital air, but only analog cable. Is there some kind of converter box for this? It would be good if it had HDMI output.
