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.

And here is something I found here:

Back to the interesting subject of composite re-composition, the HLD-X0
and HIL-C2EX specifically mention that one of their composite outputs
(the one with a BNC plug) is a "direct out" composite with a different
path than the other composite output (with a regular pin plug). The
manuals explain that nothing but TBC is applied to this "direct"
output. In particular, the Sony manual says that screen info will not
be shown through the direct output. I thought it meant the regular
composite output was a recombination, while the direct would not be. As
other decks do not mention this, i also thought it meant the other
decks only had "regular" (recombining) outputs. Can someone
explain/confirm in opposition to what these outputs are "direct", what
else than TBC is applied to the composite "normal" outputs, and if
outputs on some hi-end models (X9 etc...) could be "direct" even though
the manual doesn't mention it ? The X0 even had a flow-chart explaining
this feature, maybe someone could post a scan of it ?

Thanks. That is what I thought. Why? Well, on both the X9 and X0 RCA composite output, there will be showing the different comb settings and you can change them and that WILL effect the image. That would only be happeing if the composite output have been thru the Y/C.
I don't have any BNC to RCA cable home right now, only a BNC to BNC so I cannot test it right now. Hope to do so soon.

Btw, I have just received info that the PDI delux card have "only" a Adaptive 2/4-line comb filter for two dimensional chrominance/luminance separation. So we should maybe try to get another card with a 3D motion adaptive filter? Or are the current transfers done with the Black magic card that maybe have a 3D comb filter?
