just hooked the TWC HD cable box in two of my clients houses. So far a major disapointment. They Really compress the signal compared to off air or Sat. Digital audio only works on certain channels, not full time. When your in the reg. side of the sig. ( "S", or composite the box does not scale down the HD to 480I. When you want the channel guide to come up in the HD mode they can't do a screen overlay. Alas first generation devices are always short of the mark.
