Okay guys, I'm having the install guy come on wednesday so I need to make a decision quick. As of now I'm scheduled to get a normal Dish with the DVR unit BUT I just got that 42" 1080P Magnavox that costco was selling so I'm rethinking my DirecTV install choice. Can someone tell me exactly how big the HD dish is vs the regular one? I only have limited windows so I dont want to clutter up the look out of my apartment. Also, can anyone tell me if the newer HD20s are more reliable than the old ones? I was scared by that CNET user reviews! So many negative reviews from customers. Its my first time ordering satellite and any info you could point me to would be amazing! Oh and one question, with the HD20 can I record while watching another program?
