After finding out that upgrading from my current Digital Cable box to an HDTV box is free (yes, no additional cost) - I decided I'd go for it. They're offering 4 Channels at this present time: ABC, FOX, HBO and SHOWTIME. The idea of seeing FOX Football, Monday Night Football, and ALIAS in High Def is giving me goosebumps! I do have some questions for any of you that may have High Def service through their cable providers, especially if any of you are in the Tampa Bay area: 1. How's the quality? Does it compare to HD Service via Satellite or Antenna? 2. Does the Non-HD signal come through on the Component Video out of the HD Box, or do I also need to hook up the S-Video out to view Standard Definition material? 3. How much HD Programming has digital sound? 4. What format is most HD Programming in? 720p, 1080i or are they calling 480p "high definition"? Is most HD material in widescreen? 5. When movies are shown on HBO and Showtime in HD, are they displayed in their native Aspect Ratio? Thanks in advance to anyone who can respond.
