I finally discovered that the labeling for the PAL/NTSC slide switch is reversed, and what one would think would be the PAL position is actually NTSC. It did indeed downconvert all input resolutions to 480i. However, using my DirecTV Receiver/DVR as the source produced poor results with color banding, shifting and some interference patterns. I then tried it on an old non-upconverting Pioneer Elite DVD player (480p) the results were nearly perfect. So, I guess it just doesn't like the component output from my DirecTV receiver, which is what I inended to use it with. So, I really didn't get a chance to check the copy protection issue as I plan to return it for refund. But. it looks like depending on the component video source, it may work OK for some. YMMV.
Updated review for anyone considering the Lenkeng Video Converter (alternately referred to as either LKV7611 or "YPBPR to AV". I just bought one, and I am quite disappointed - my results were very similar to those above, although my NTSC/PAL switch was labeled correctly.
I have problems with both color banding/interference and reduced brightness of the output. The color banding/interference problem is ONLY on the s-vid out and does not appear on the composite out. I can confirm, however, that there is no copy protection on either output signal.
I tested with component output from several DVD players and my high definition TiVo. I checked the Video Converter output side-by-side with the raw s-vid output from each test box for PQ when either used as input to a Panasonic EA18 DVD recorder or fed directly into a Sony plasma TV.
Bottom line is that when fed directly into my Sony plasma TV, BOTH Video Converter outputs looked identical and of similar quality to unaltered composite output, but without any copy protection signal.
When viewed directly on the plasma TV, the s-vid output PQ is just slightly worse than the s-vid feed taken directly from any of the source units (about on par with a straight composite feed). The composite output of the Video Converter is almost identical to the direct feed composite, but it actually looks just a tiny bit better when viewed very close to the screen due to slight blurring of the jagged edges. When fed directly into the TV, neither Video Converter output signals showed any color banding/interference or brightness shift.
Unfortunately, there is absolutely no reason to ever feed the output of the Video Converter directly into a TV, so this has no value!
When output from the Video Converter was fed into a Panasonic EA18 DVD recorder, the results were completely unsatisfactory
. Both the composite and s-vid outputs were considerably darker than a direct s-vid or composite feed, causing skin tones to be quite orange. In addition to that problem, the s-vid output exhibited significant color banding/interference patterns (which were there on both the pass-through video and on a recorded DVD. Although the Video Converter does allow one to record copy protected sources, such as a commercial DVD or flagged cable signals, this is meaningless because the result, at least on my EA18 recorder, is unacceptable!
The new TiVos no longer have any s-vid outputs at all, and many cable companies are copy protecting virtually all signals, so I had hoped this would be a cost effective solution. Alas no; it is worthless
. This is one of those situations where you get less than you pay for. I hope this information helps prevent others from wasting $50 on this thing.
