Can anyone tell me if there is a good comb filter in the Panasonic DMR-E60? I have one, and have my player hooked up to it to record discs, but I don't use it for pass through at the moment. Is it worth tinkering with? Also, if I do use it as a comb filter, should I output from the DMR to my TV from the Composite, S-Video or Component?

I'm not sure if it does, or not, but do you have a Video Essentials LD to test it with? Also, WHY would you output from the DMR with composite? You want to separate Y/C just to recombine them? Either s-video or component. TLK

Either s-video or component. TLK As of right now I actually do not own a copy of Video Essentials, I haven't seen one with decent shipping to Canada pop up lately, but I am looking. I figured I wouldn't want to output through Composite after the comb filter, I just wasn't sure, and figured I'd ask. I currently output through Component, but wasn't sure if that was the best choice.

I wanted to test my Panasonic DMR-ES10's comb filter in the most " pure" way, so I fed it the composite output of my Panasonic DVD-S29 playing Digital Video Essentials. I then took the s-video output of my Panasonic DMR-ES10 and fed it to my Hauppauge USB-Live2 capture card. Everything was reverted to default/factory settings prior to the capture. Here are the results: StillMovingDownload a 31-frame-long sample here: https://www.dropbox.com/s/fbt23kkwslnxz ... Sample.aviThe sample is losslessly-compressed with the Lagarith codec and is set to play at 1fps. It's ~5.8MB. Enjoy!

In a DVD recorder they always get split to component and component has no bandwidth restrictions on its outputs, unlike S-Video. There is only one demodulation of the chroma after the S-Video input or the composite inputs trip through the comb filter, so again, component is always the choice when available.

I will check this out with DVE and the DMR-E10 and post screenshots when I can. @acuozzo If you said the first frame there was a still from the actual VOB file, I would have believed you. About VE vs DVE again: which will have the better chroma? Analog, or digital 4:2:0?

About VE vs DVE again: which will have the better chroma? Analog, or digital 4:2:0? Digital 4:2:0 and 4:2:2 have far better chroma than composite NTSC in all aspects except vertical chroma resolution - vertical chroma resolution in composite NTSC is 480 lines but cut in half or less if passed through any kind of comb filter except 3D - and then it will be 480 only when there is no motion. But, there's nothing you can do about it so it's nothing to worry about - we are so insensitive to chroma that you won't see a difference between 480 vertical lines of chroma and 240- horizontal chroma resolution is what matters in comb filters. And 4:2:0 and 4:2:2 don't apply to LaserDisc's since they are analog - no 4:2:0 source was ever used to make an LD. Now, the difference between AVS and DVE is that DVE has specific patterns for testing chroma res and comb filters, AVS does not. The amount of chroma noise a disc has depends on its pressing quality - some AVS discs were noisy since the disc was pressed much earlier than DVE. My Disctronics pressing of AVS has quite noisy chroma, but Pioneer's pressing was better - DVE was made when disc quality had improved immensely. Still, both discs are good but DVE has the more useful patterns and AVS is just more interesting to watch.

I chose DVE over VE because I wanted the most pure noise-free signal possible for testing. Oh, I totally agree - capturing 4:2:2 is always best - 4:4:4 would be the ultimate, which some of Sony's HDCAM formats do. True Constant Luminance processing would be good for all digital formats because it would make low color resolution look like higher resolution. Off topic.... I got the discs - the Sony IDTV "Little Dreamers" disc from 1988, and pressed by Sony Japan has the absolute best PQ I have EVER seen from an LD. For those who dont know what I'm talking about, it's a demo disc for Sony's first progressive scan TV, which they introduced in 1988 and called Digital Trinitron - it was a failure due to the deinterlacing and digital comb filtering not being quite advanced enough, but the demo disc is amazing, if weird in that Japanese way. It was shot in the analog Sony HDVS Hi-Vision system and down-converted to LaserDisc and WOW. It looks like an amazing DVD.

I still wonder how MSB got rid of the missing image on the right side of the pic on the Runco... All their processing seems to come AFTER the digital Panasonic processing. Wish I was an E.E. and could figure it out. BTW, did you see that there are two Runco LJR-II's on eBay? One is the DA model with the digital converter built in, like mine, the other is the studio without the DA. It appears neither has a remote.
