We have an HD TV, we get a few HD cable channels, mostly repeats from the ones we can get off the air. Currently Comcast charges $5.00 a month for HD channels, but there really should be more. Hardly any of the basic cable channels are in HD. I really hope that more HD channels go online as the difference from standard to HD is really amazing.
Some channels I'd love to see in HD are ... the Travel Channel, TBS, USA, TVLand, and of course, more of the premium channels.
