I guess those D60X players have really, REALLY noisy designs? I tried the ES25 again with my Panasonic LX-900, and had much better results.
Cross-color artifacts almost completely disappeared when using the S&W test pattern and the orb stopped moving. Good with the colors and dot-crawl as well. Does the picture flash or blink at all?

No artifacting at all in the boxes surrounding the orb, and the rainbows disappear completely when it stops. I wonder if any of the Sony DVD recorders used that comb filter?

Made a gif of the Snell & Wilcox moving orb through the Panasonic DMR-ES25 (using Panasonic LX-900u. (click to open page with gif) So it's a pretty good filter as you can see. Doesn't completely get rid of cross-color, but still reduces it pretty well. Also nice colors. I'll try to do one of the Toshiba D-RW2 soon.

I think I'll do the same with my new Onkyo NR-818. TLK

sdraper wrote: Would anything like this be better than a CRT's filter? I'm intrigued by the RCA recorder for both LD and VHS having component/s-video outs. Depends on the CRT. Like I mentioned before, the comb filter in my KV-40XBR800 does an absolutely amazing job with both dot crawl and cross-color (rainbow effect.) When feeding the LX-900u to it via composite, the only cross-color that shows up is when the S&W orb is moving. Once it stops, no artifacting whatsoever anywhere on the screen. Using the comb filter my parents KV-32FS120, it's not as good. The artifacting is hardly affected at all. I'm just being more experimental now because of the knowledge that Disclord dropped with he color tests in the S&W test pattern. I don't recall the S&W color tests being fully realized when using the internal filter on the KV-40XBR800 (perhaps in turning back the cross-color artifacting, color reproduction is affected?) Look at the color test bars in the bottom of the screen for that RCA DVD recorder snapshot . . . Then look at the color test bars in the gif I posted earlier, and you'll see the difference. Some of the comb filters in these DVD Recorders give better colors while doing a decent job with artifacting. So I like to experiment a bit.

reject902 wrote: FYI: For anyone interested in trying the Toshiba DR430- the 3D comb filter (if it's in there) is absolutely awful. Snell & Wilcox rainbows terribly even when not moving. Now, the color correction and upscaling on it 's pretty good.
Now, I really like how the DVR600 performs. It does good color correction, upscaling and S&W shows rainbows only when moving. They can be had pretty cheap on ebay now too. Thanks for the heads up. I was actually looking at them on eBay just now.

Basically I'm wondering if I can cheap out and avoid buying the VE LD when I already have the (HD) DVD combo disc to test. If you use the RCA NTSC composite out of your DVD player you can use the zone plate test on the DVD to test external comb filters - but you can't check the internal comb filter or the chroma/luma resolution your LaserDisc player outputs

According to the service manuals, they both use the developed-in-house Panasonic C1AB00001979 for comb filtering. DMR-ES10 (P/PC) Service Manual: http://www.tgohome.com/ServiceManuals/P ... BSM%5D.pdfDMR-ES25 (P/PC) Service Manual: http://www.encompassparts.com/shop/rese ... MRES25.pdfDo you think " PC" stands for Canada? Yup, I had to amend my review of the ES25 DVD recorder when I tried it with another LD player. Much better results. I'm hoping to get a DMR-ES45V (the same model as the ES25, but with a VCR as well) to see if it has the closed captioning capabilities that the E48-VK has, but with the better comb filter (the E48VK filter is crap.) Dunno about the PC though. I checked Canadian Panasonic site. DMR series of recorders do not end with PC or C.

Video Standards only problem is that it has nothing comparable to the Snell & Wilcox zone plate pattern that tests a players or comb filter's color resolution, diagonal resolution and cross color artifacts.
