FIrst, I love how people submit a reviewon theur first ever box....nothing to compare it too.
Anyway, this is my third DVR, I have had a Sony Ultimate TV DVR which niether Tivo or DTV chave yet to come close to in terms of functionalilty. I have had the Tivo DVR nice box and well thought out, then the DTV R15, the worse of the three.
1. No 30 second instant skip instead they use a 30 second ff which takes forever to skip through commercials.
2. Limit of 50 programs in playlist, not a limitation with Tivo or UTV. You can hit 50 before your even 25% through programming your series list (SL).
3. Big limitation - cannot handle more ten one series list per program title, so forget about recording a series like mash or scrubs on more then one channel.
4. Manual recordings cannot be modified
5. Primitive search options compared to Tivo or UTV due to the simplified program guide they subscribe too and just poor or limitied application programming.
6. Suffers from overheating problems even in open air environment in a room kept at 69 degrees causing it to lock up or reboot.
7. Suffers from spontaneous resets causing loss of programs being recorded.
8. Keeps limited program information on recorded programs so pressing info for instance to see who the actors are in the movie your recorded will be missing
9. Will not allow for limiting searches to your favorites channels.
10. Awe if you still are thinking of buying one after all the above, listing more won't matter.
This box is one of DTV's first boxes after they dumped Tivo and tried to go their own. After UTV and TIVO you would have thought their marketing and programing people would have taken the best of all those other boxes and created one that made you WANT to use thiers, instead they created a box that makes you want to pay more for a Tivo box or go to ebay and buy a used Tivo or UTV box.
Of the three I have this one is in the room I use the least, my next box will be a Tivo.
Good luck!
