What would really solve this situation is if Dish somehow implemented a Profiles feature. I remember the now dead SezMe DVR and at its heart was the extremely elegant Profiles feature based on different colors and letters for at least four different members of a household. Just about every setting was unique to each of the profiles and only the recordings made with in a profile would display in the DVR list for that same profile. No mixing of all the recordings in one display. That was a long time ago and I remember thinking that that profiles feature was the best thing to ever come to DVR's for multi household members since the DVR itself! If Dish could come up with a profile feature, especially for the 16 tuner Hopper 3, that would be far easier than remembering to use the Folders assignment each time a different person wanted to set a DVR timer. I know because I often forget to assign some recordings of the other DVR to my backup folder or even my own system of folders.
OP, consider yourself lucky that you can at least build a unique list of channels on Dish clients, the Joey's. Wiith TiVo the list that you build at the DVR also becomes the default channels list at the connected client Mini. In fact, there is no way at the Tivo Mini client to access any of the channel settings whatsoever. So, if the household member at the Mini client doesn't like the Favorites that were set up by the other household member who uses the main TiVo DVR, then the person viewing at the Mini is out of luck, as is everyone else using their own Mini client connected to that same DVR. There are a few other things that the Tivo Mini cannot do that the TiVo DVR does, but I don't want to take the time to get into them here.
What I will say is that the Dish Joey's do absolutely everything the Hopper DVR can do except for the Bar Mode 4-channel PIP and YouTube, which is more and nearly identical as if you were at the DVR than what the Tivo Mini provides. Further, TiVo makes no distinction of different stop and resume points based upon the DVR and each TiVo Mini client paired to the DVR. That last one is a particularly sore point with me, because other people will watch the same recording but then stop it at a different point, and then I have no choice but to pick it up from the last viewers stop Point rather than my stop point I made earlier, if all of that make sense to you. And there is more than I've mentioned so far, so my earlier statement about not taking too much time to get into the whole list still holds true.
. However, there is no doubt that the Tivo Mini client is absolutely the best
accessory that TiVo has ever developed and its entire history, and I highly recommend using the TiVo Mini clients for their main purpose because it's a lot cheaper than getting another DVR box just to watch the same content in another room.
