Are you saying then that it's important to have three or more hours available on the guide? Like I said, it would be nice to have more information available at once, but I care more about 1) the programming, and 2) picture quality.
To *ME* more guide info is important.. and obviously more important to me than others (but I'm not the only former Dish sub to mention it)

for channel surfing, sure 1.5 hours is probably fine (ie. what will I watch now/next)... but (chicken/egg) for finding material to DVR (crap.. what night was that on.. I know it's primetime.. but what timeslot?!?!).. I would find 3 (or more) hrs much more useful.
And for you PQ is important... for me, I truly don't remember noticing any difference as I moved from Dish to DTV... I've had the same 47" 1080p LCD for ~4 years... perhaps if/when I switch back, maybe I'd notice something.. I dunno. I'm not sure what is supposedly "better"... ie. does DTV actually send a higher bitrate? Or they have better encoders, or just happen to deliver a picture with a color temp, contrast, etc, that ppl seem to like better? I suppose that is a topic unto itself.
As for programming, the wife's one gotta-have is Bravo, and DTV offers that in the lowest tier(s), vs. Dish forcing you to a mid-level tier... so DTV has the edge there. Other than that, I'm cheap enough that there wasn't any other programming that made a difference (to us) at our lower tier levels (1-2 ESPN channels is enough to satisfy our sports needs... the more die-hard sports offerings aren't relevant to us, but I realize they do make a difference for many others).. Alas, the little that I've looked also suggests that (if forced to the middle tier) Dish won't have the pricing edge that it used to. (I'm cheap, I admit it... I like having a cheaper alternative, even if that requires trade-offs)
The other thing that _might_ keep me with DTV (I can hear the screams now

) would be the wireless clients... that has a certain appeal, at least at the detail-free level.. would need to find out more specifics, and no idea if Dish does/will have anything comparable, and/or how many issues the DTV wireless clients have (or wireless clients in general)
Really tho (to get back on topic).. IMO, it isn't whether you, me, or any other current DTV sub *likes* anything... ie. we are here to help a "switcher" make an informed decision and ultimately be happy (or as happy as possible) whichever way they go. The switcher is the only who needs to "get" what we each like or dislike. They can choose the things that resonate with their personal lists of what is/not important to them.
