First, I am not a troll.
I keep reading how people hate the R15 and want to go back to their Tivo based DVR's so I just wanted to give my feelings.
I have used 2 cable DVR's and the R15 and installed the HR10-250 Tivo based DVR two weeks ago. This is the first time I have had a Tivo based DVR and I hate it. Sure it has some nice features but just the basics are terrible. Perhaps I haven't found the solutions to the problems I identified below but right now I can't wait for the D* based HR20-250 to come out. If it wasn't for wanting to watch my HD locals OTA, I'd probably use the R15 primarily.
Pros:

Pros:
- I like the beeps and sounds.
- I can't find a way to have it globally save all the shows I record until I delete them. I know I can do it per show but there has to be a global setting somewhere instead of the 3 days, but I haven't found it yet. I almost lost a show last night when I saw the ! in the List icon and decided to check it out.
- Can't see TV show while in guide since it covers most of the screen, and when in anything other than guide like List can't see or hear anything
- Loading guide is way too slow
- Seems like when a remote button is pressed, the unit doesn't react immediately. I sometimes have to queue up button presses before I see the actions happen, like changing the view of the guide in the Info options to a later time.
- Recording a show takes way too long as I wait for the "Please wait" icon to leave. The R15 simply puts a R in the guide quickly and you're done.
- Recording shows later in the day sometimes brings you back to the current time. This morning I wanted to record all the shows I wanted for tonight. I got the guide to the current time and recorded my first show. I wanted to change the option to not delete until I tell it to and when I was done with that, the guide was back to this morning's time. Aarggh! I once again slowly got to the guide for tonight and this time forgot about the delete option just so the guide would stay there.
- Remote is difficult to hold because it's skinny in the middle. When I need to fast forward, I have to hold it with two hands so I can fast forward and then press Play. Fortunately I have a Harmony remote that has resolved that problem.
- No caller id
- This is D*'s fault. I think I have read through the manual but it doesn't explain everything. For example, the Thumbs Up and Thumbs Down. All the manual says is to press it to let the DVR know you like the show. What about the 2 or 3 presses? Luckily I have a Tivo friend who informed me what the 2 or 3 mean.
