Can anyone comment on the differences between Dish Network's PVR and TIVO? I am currently a dish subscriber and satisfied. I also have TIVO. However I would like to upgrade my Dish to HDTV or to a receiver with a digital audio output. The one I have doesn't have this, and I think its because I bought the lower end receiver to be compatible with my TIVO. The feature I can't live without on TIVO is the season pass - tivo's ability to follow a show if it changes nights. Can Dish's PVR do this? How about searching for programming? Can Dish's PVR do a search based on a keyword like Tivo can? I personally don't care if commercials are removed. I can fast forward through them so I'm not really keen on that feature by replay. My other option is to change to Directv although there is some programming on Dish Network that I can't get on directv Any ideas?
