I have been doing some research on widescreen tv's lately and have found myself with more questions than answers. 1. Is there a picture quality difference between rear projection CRT, rear projection DLP and Plasma (I can't afford forward projection)? I have done some comparison viewing at the local stores and am of the opinion that the plasma screens look better than most CRT's, however, the higher end projection CRTs are very close, if not better. I have not seen any DLP's but have read that they are inferior to CRT's, is this true? 2. Should I be concerned with the longevity of a plasma screen? I read that pixels can be damaged from constant images (e.g. letterbox). 3. My HT will be in an upstairs game room. Provided that I can fit a large projection tv up the stairs, should I be concerned that some jarring may misallign the guns? How hard are these to calibrate if this does happen? 4. With all of the proprietary gizmos and do-ads of the different brands, what specification is the best to look at when comparing these types of tv's? 5. What does the i or p suffix to 1080 mean? 6. If I get digital cable will this give me HDTV if my tv is "HDTV Upgradeable"? That's all I can think of for now. Thanks in advance, for helping out a newbie in his quest for HT bliss!
