Well, that say really nothing. It is two seperate outputs and of course they will have different adjustments.
But try what I said before. Take composite out from you HLD-X9 and change the comb filter. I have always wonder why I could change the comb filter and have an effect on the picture if the signal is a pure composite. And here we maybe have the answer. I will try to get a BNC to RCA cabel tomorrow and try the BNC output.
Can there really be any other answer than that the output is not recombining?

I can tell you that on the X9's video board, there is an adjustment that increases the level of "sharpness" by increasing the frequency response. There are two seperate dedicated adjustments, one for S-video output and one for composite output. If the X9's composite output just came from recombining the S-video output, then there would be no need to have a dedicated adjustment for composite. I think this indicates that there are two seperate signal paths on the X9, one S-video and one composite. It's always been accepted for a long time that the X9 did have a "pure" composite output and did not just recombine the S-video. I think folks like Kurtis Bahr and Ivar documented this. I will ask another gentleman I know and see if he has any thoughts on it.

I don't think it is recombing. If the composite output was a recombination of the S-video, why would they have dedicated composite adjustments on the video board? If the composite can from the S-video, the S-video adjustment that is also present would be all that was needed. A dedicated composite adjustment wouldnt' be needed because it would have already been done on the S-video signal path. I'll email a laserdisc tech I know. He is the best in the business in the US. It is not Kurtis Bahr, but Duncan Hunter. Duncan has worked on my X9 and is well versed in ld theory and about the adjustments on the X9's video board. I had my X9 hooked to my pioneer elite HDTV when I first got it for testing purposes since the Elite HDTV has the same comb filter. The X9's comb filter settings had no effect on the picture as far as I could see and I tried using the HR, Normal, and C-wide modes under the Standard setting. This was running composite direct to the HDTV. I'm now using my X9 with an Iscan HD+ using S-video. I'll have to try hooking up the composite again and see if I notice anything.
