I swtiched to Direct because I wanted more HD channels and a lower monthly bill, but I knew there would be some trade-offs and here are the ones I have discovered so far. I knew about some of them in advance, but not about others.
1. To watch TV in another room, but have the receivers both in the first room, you will need to buy the R15 DVR so that you can use the remote through walls. Unlike the 622--only needed the one receiver to accomplish this and it had 2 remotes--one being RF.
2. You will have to buy the RF remote, as it does not come standard with the HR 20 or the R15, another unexpected $25.
3. In the HD DVR, you can't see 3 hours of the guide--you are stuck with 1 1/2 hrs only and no way to customize.
4. Since I have to have 2 DVR's, I can't watch on TV 2 what I recorded on TV1.
5. On TV 2, with the R15, I cannot see the HD only channels--they will only be viewable on the HR 20 in Room 1 with the HD Tv. With Dish I could watch the HD channels on TV 2, if only in SD.
6. I can't program the DVR's to autotune to a specific channel only or a reminder--I have to program them to Record and that's it.
7. I do not have all the customizable favorites that the 622 had--I only have 2--Custom 1 and Custom 2.
8. On the R15 standard DVR, the "Channels I subscribe to" does not work--I cannot see only the channels I subscribe to. I have to customize one of my 2 custom favorites list to do that.
9. The DISH 622 RF coax output not only gave me the signal for the Tuner 2 (SD), it also had the Tuner 1 signal that went to my other TV's in other parts of the house. The HR20 has NO RF Coax output--it cannot be fed to anywhere else in the house that is a significant distance using coax.
10. The external Hard Drive you had with your 622 that used a USB port cannot be used with the HR 20 HD DVR--its USB port is inactive.
11. Descriptions for programs do not include the first date that the episode played.
12. I find no Video on Demand that can be accessed directly by downloading from the Direct TV satellite. I was told I could access via the internet, which is impossible for my Satellite (Wild Blue) internet--only allows me 7500-12000 Mb/month.
13. If you are unfortunate enough to get a HR 21, you will NOT be able to integrate OTA locals so that they blend with your guide and are recordable. Imagine that! You'd better have your HD locals coming from Direct to do this. OR you must insist on the HR 20 BEFORE you install or don't accept the install unless they trade out for the HR 20 which does have an OTA input.
Well, this is just a start. Maybe other DISH ditchers can add others. Or maybe Direct veterans can give me work-arounds for the above points.
I will learn to live with this over the next 2 years, but, if DISH gets all the HD Direct has, survives the AT&T take-over, I will probably return in 2 years, but I wanted the HD worse than I wanted a top-notch interface, but I had a few surprises and maybe will have more, as I have only been with Direct for 24 hours. But I hope to spend more time watching HD than fooling with the equipment.
Good luck, Dish Ditchers, but hey--I love the Smithsonian HD, CNN HD and the native pass-through.
