I've bought one of these, and I think this review is quite accurate. I have some further observations:
I think the problem with the "tuner" is really a problem with the unit's processor that processes digital video. I.e, the tuner itself is probably fine (the part that actually RECEIVES the digital TV video data), however I concur that the unit does not PROCESS this digital video data as well as it might. It has the same problems when displaying a pre-recorded program (from a USB disk), and of course the "tuner" per se is not used when playing pre-recorded material. So far, I've noticed two main problems with the video processing:
1. Artifacts (jerkiness, and blockiness)
Some of this may be due to the actual DVB broadcast itself, however I notice an improvement when I use a PC to display the same file, over HDMI. (still not perfect, but it's definitely better). I am using the VLC player with "post processing" disabled. (I haven't gone into every menu and ensured that it is not doing *some* kind of post processing, mind you) Now, having said this, sometimes I encounter a transmission that displays very well. So, perhaps the TV is not coping well with some kinds of transmissions, and/or marginal quality MPEG.
2. A clipping of shadow tones
This is probably the same problem that the reviewer observed. (lack of shadow tone detail) I was able to make an improvement by adjusting brightness and contrast, HOWEVER, the problem seems to disappear when I use my PC!
So, I concur with the reviewer that the screen itself is good, and the problems SEEM to be with the digital video processor in the TV. Hopefully OHKI can make some improvements with software updates.
A few other points:
1. Poor remote control range.
I am sitting 3 metres away, yet the remote has to be lined up quite directly with the receiver on the TV. I.e, if I move a bit to the side, I then have to lean forward, even though I am still aiming directly at the area of the TV which seems to have the receiver.
2. No support for large (> 4GB) video files
Despite the manual stating that the USB disk can be formatted with NTFS, I have not yet been able to get this to work. If I plug in an NTFS formatted disk, the TV pops up a message saying that the disk needs to be formatted, and it does not provide an NTFS option. The good news is that the TV automatically splits files into smaller chunks when IT is doing the recording, so at least it is possible to make long recordings with the TV.
3. Some HD video files DO work
Despite the reviewer stating that HD video files do not work, I have had some success, even with full HD files. I do have one that does not work, and this may be because it uses DTS audio. DTS is not listed as a supported audio format in the manual.
