"If you like the R10 you won't be happy with the R15"0.5 starson by ncrdave
Pros: They're free when you pay the shipping from DirecTV - That should be your first clue
Cons: Awful user interface
Summary: I've had a DirecTV R10 for about a year and it has changed the way I watch TV. It's great! I liked it so well, I wanted to change one of my other DirecTV boxes to an R10. I called DirecTV and found that they no longer offer the R10 but have the R15 to replace it with more recording time. I started looking at reviews and couldn't even find one positive review for the R15. Several said to get a used R10 if you could find one. I did find them on eBay for a pretty good price. I got one that works fine, but tried to buy 2 more and found that DirecTV obviously doesn't want to make it easy. If you want to buy a used R10, get the Receiver ID, the serial number, and the access card number and call DirecTV with this information to see if they will even issue an access card for it before you buy it. One was associated with an account that owed DirecTV money and they would not issue a new card. Another one, they said was aleady active on another account and wouldn't even tell me if they would activate it until I got the serial number for them. If you buy one on eBay, be sure to get those numbers, and check with DirecTV before buying.
In my talks with DirecTV they convinced me to try an R15 (hey it was almost free!). They came and hooked it up about 10 days ago. Before the installer left, the R15 was already acting up. Over the next day or two it continually would go to a blue screen and start it's 5 minute reloading proceedure. I called DirecTV and told them about it. They said that was a known issue and would replace it. They did and I have the new one which seems to work without reloading constantly, BUT... If you never tried an R10 you might be "satisfied" with the R15. But, if you have used the R10, I guarantee you won't like the R15! There is no slow motion forward. There is no way to rewind to the beginning or any other point easily and quickly. You would think it was a VCR rewinding tape to get back. The buttons on the remote seem to not work well. You press a button once and it acts like you pressed it twice. Fast forward through commercials becomes a chore when you try to stop just after them. Bottom line here - get an R10. I'm going to get another one and let DirecTV have their R15 back. If you have to have more recording time, there are upgraded R10s available with large hard drives. These seem quite pricey - I would guess that's because they work!
