Question: Can this be used with a led flat screen tv that already has a built in digital tuner? Will it cause picture quality loss on a led tv?
Document: When my Samsung tuner for my projector crapped out, I went looking for a new one. I had purchased an Iview box and returned it due to the poor picture quality. This unit has all the features of the iview unit but has a much cleaner sharper picture as well as a second tuner. The  one thing everyone seems to complain about is the narrow angle that the remote can be used. It is definitely pretty tight, but not unuseable. Overall it's a great unit with some nice features.
I needed digital video recording and a tuner, and this product seemed to fit the bill at a reasonable price. So far, this device has done everything I needed it to do. The time-shifting is a bit tricky, but I really think it's a firmware issue and correctable with future patches. Overall, that's more of a minor concern for me. I'm more concerned about the recorded picture quality which is pretty damn good. The image is crisp and sharp. The colors are pretty vibrant.
I started out looking for just a digital tuner to use with our video projector in our media room since it does not have a built in tuner. Couldn't find anything that filled my requirements for just a HD digital tuner so bought this even though I doubt I'll by an external hard drive to record any programs.
Live tv pause  or  ""time sync "  doesnt work,  otherwise it works as promised.strong tuner, easy set up easy to follow menu items. once video is fully recorded, playback works just as any other dvr.in my case where I watch tv through a projector, this item filled a need very nicely, excellent clarity on 8ft screen from free over air hd broadcast.
I was disappointed overall with this unit. Although the tuner worked okay and the recorder was okay,  the use of free OTA program was what was not working well. Not all stations send that out uniformly. Also the way it put that on the screen did not come thru the video out. This makes it impossible to use with my Slingbox as I had hoped. As an alternative I got a Magnavox DVR with a 1 TB hard drive built in. That tuner works great with Slingbox and will be fine.
I guess this thing did what it said. Problem was it had no way to get tv program guide. You have to subscribe to an outside vendor for a guide. And it has no wifi. I couldn't get it to do anything but record what I was already watching. Too hard for the casual user to use although I did try - but there is no technical manual, just the little few page getting started guide.
Strong signal reception on both tuners. Flexible timer recording methods, easy to use electronic programming guide from OTA channels. Smooth time-shifting and live pause. Nice QUICK menu key and powerful FAV (Favorites) key. Good built-in media player and the video quality from HDMI output is just great.
I am used to using a direct tv DVR for years now. When I discontinued their service I needed an alternative to record. I really love the product. It has a few minor flaws but overall it's a great product. The unit sometimes sticks while recording and does not turn off and the recorded program isn't where it should be in the menu, making it not possible to delete. That does not happen often, but it has on a couple occasions happened.
Easy hookup. On screen configuration. 2 cable connection. Records cable or over the air tv. Only drawback is fast forward is a bit buggy. Sometimes it freezes. Can fast forward at 2, 4, 8, 16, or 32 speed. No slow motion that I found and rewind has same bug as fast forward. Very minor issues considering the price and savings over cable DVR's that have their own issues. I would highly recommend this DVR .
I've used and had this product for roughly a year now so I'd say that I'm in a good position to write a realistic review about it.The goods:-This tuner's quality is pretty good. I cannot complain about the reception or the video quality with OTA, it's pretty solid on that front.-The UI is not the most elegant, but it's better than most boxes out there.
Answer: Yes , using the  HDMI inputs gets true HD very clear picture . I like mine for OTA reception really nice no loss of  picture quality here.
