well on the last part I agree with you , with digital you either get a picture or not but as an engineer I prefer digital over analog any day. well properly configured digital not most of the crap we get here in NA. As an example, I just enjoyed the World Track and Field Championships held during these days in Berlin via Hispasat 30W on Tele Rebelde (live from 8 am to 4pm), the cuban channel (well I had cuban friends over and most did not speak english otherwise I would have switched to the NBC Sports coverage from 2 to 4 pm in HD), but any how, that digital cuban mux is properly using enough bandwith and the SD picture was high quality (kudos to the German Broadcaster on that of course) but my point is , if you try using , Universal Sports (a subchannel of NBC on digital) or some other tv channels via FTA (not the NBC master signals) you will see a lot of macroblocking on sports events. They want to save money rather than give you an optimal service. I do not blame them this is northa america and everyone wants to drive a mercedes benz and those are expensive , lol.
This is all off topic now but digital stuff is actually not only very good but the best you just have not had the opportunity to watch it in its glory.
