Is there any way to get better video quality out of the NR2? I was hoping for near broadcast quality, but even on "superfine" the pixelation is extensive.

I have been experiencing the same problem when recording VGA in super fine mode. PLayback on a TV has pixelation and is not of the quality I would have expected.
Im also noticing the playback does not have smooth fluid motion and I detect a jerky movement quality to the playback video when played back on a TV.
I can not detect these same problem issues when played back on the 442 player.

First, the video quality will depend on the quality of your source. What source are you recording from? If it is a DVD, you should not see many artifacts if any, if you record from a cable box, some channels have a much cleaner signal than others.
If this is not the source, make sure you have the last firmware update installed, the quality increases pretty much for every new release. Video playback is up to D1 (DVD quality), so you will be able to download and watch DiVX files for example that will look as good as a DVD. Just remember that recording quality will never be as good as a DVR like a TiVo though(even if we were encoding in MPEG2 instead of MPEG4) as the Recorder 2 encodes the analog video signal coming out of the video source. The artifacts you see are moslty due to the noise coming from the analog signal. In the case of a very noisy channel, you might be better of recording at QVGA resolution rather than VGA. (that happens with the 442 as well, sometimes recording at QVGA resolution look better than at HVGA resolution).

I have tried recording from my dish Network DVR and DVD Player.
The Video quality recorded on the R2 looks Great on my Handheld but is just not up to snuff when played back on a TV.
I agree with FJ, using QVGA looks about the Best when played back on my TV.
I hope the OSD can playback VGA on a TV with quality results.

The video quality of the recorder 2 at 640 x 480 superfine is very good. There is no other product on the market in its price range that will do real time video capture converting. Make sure that your recording source is free of any interference.

Video qulaity looks great when R2 recordings are played back on my 442 built in screen but No matter what I try I can not get good quality playback on a 27 inch TV using the Recorder 2 even in VGA superfine recording mode. My DVD recorder using the same recording source in comparison looks great when displayed on a TV. Maybe I just have a bad recorder 2 if others are getting good quality results when displayed on a standard def TV. My main use has been to record content and then transfer to my 442 for playing back on TV's at Hotels when on Travel. The quality has been such a disapointment that im better off recording to DVD's and using my laptop to connect to the TV for playback. Am I expecting too high a level of video recording quality from the R2 and 442 to expect it to be on Par with a basic settop DVD recorder? |

I bought my nr2 three weeks ago and have noticed the same video picture qualities issues expressed here on this thread. Things like the Neuros splash-screen is skewed to right, recording VGA superfine for TV playback is no way near DVD quality (my VCR w/HighQuality tape record/playback is better than the nr2 on my TV) and the included cables w/miniplug connectors are very, very susceptible to interference.
Having said all that, I'm still very happy with the nr2 because I didn't buy it for use with my 27" TV. I have a JVC DVR and VCR for doing that. I bought it for use with my PSP and to that end, I very satisfied with its performance. I consider the nr2 captures for audio/video playback on my PSP to be outstanding.

I agree the R2 is designed for use with portable devices and it does shine in that area. Im alittle annoyed however That Neuros also claims its near DVD quality when displayed on a TV and I can't get results anywhere close. My main intrest in the 442 and R2 was for a compact device that can record and playback content on Hotel TV sets when on Travel. So far my results have proved poor from both devices. |

Video quality is also greatly reduced by poor cables, especially poor
grounding at the PCB end.
You could have poor solder joints at your board level.
Reading both your comments about poor quality, have either changed
your cables? If so, the cold solder joint is most likely.
Tiling, skewing, is a typical observation of this problem.
Our recorder systems were measured (spatial registration, valid region estimation, system gain and level offset, temporal registration)and received good marks.
Our Neuros systems are very close to DVD quality.

If your getting near DVD quality playback to a TV than maybe the problem is just poor build quality of the R2. I did have alot of problems with the cable connection to the unit initially and noise rolling thru the video that I was able to correct. Playback on a TV is still poor quality however so I assume I just have a Bad R2 based on your feedback. |

I get very good quality at 640x480, super-fine. This is with the supplied cables. I can sometimes get a wide, verticle, bar that cycles slowly from left to right on the screen. I attribute this to "hum", which is probably a result of the lower-quality connectors on the R2, and *probably* correctable with a higher-quality cable.
