VHS capture (through dvd recorder) in Composite or S-video ? (Avisynth comparison)

Hi,
I have to capture a Pal VHS with an Hauppauge PVR-150 (I do this with Virtual VCR in Lagarith yuy2) and I have 3 possible connections between VCR and PVR-150 ;
-direct connection ;
1) composite using a scart to composite adapter (only scart output on this VCR)

-standalone dvd recorder between VCR and PVR-150 ; dvd not recording of course, just switched on to let pass the signal to use its TBC better than PVR-150's TBC (especially on a Secam VHS I captured some time ago, maybe less useful with Pal) ; VCR connected with Scart to Dvd recorder (VCR probably sending a composite signal on scart), but 2 solutions for dvd output to PVR-150 ;
2) composite
3) s-video

I read that s-video was not very useful for VHS but also that sometimes, the Y/C separation could be best done by the player than by the capture card.
So I made tests ; I don't see any differences but as my eyes are not perfect, I'd like to be sure which is the best with this equipment.

Here are 3 extracts in Lagarith yuy2 ;
1) composite without dvd ;

There is a little header problem with this video due to the Hauppauge filter used by VirtualVCR ; the framerate detected is 29.97 while it's actually 25 fps, just change it with Virtual Dub (video, framerate, source rate ... and save in direct stream copy).

2) composite with dvd ;

3) s-video with dvd ;

You can find Lagarith codec there ;

Why do I ask it in Avisynth section ?
Because I'd like to know how to analyze these videos with Avisynth to measure precisely differences between these captures (if there are differences, I think to luma and chroma levels) to choose the best way to capture this VHS.
I will also need to filter this video but let's begin with the capture connection's question.
