Now you got me thinking.
I presume you would still use the Laserdisc player composite out if feeding a VHS recorder? In other words, doesn't VHS record composite?. What about S-VHS? Something tells me S-VHS handles Y and C separately, is this correct? What about DVD-R?
Is it safe to presume that S-VHS and DVD-R recorders could be looked at the same as TV sets, and that the recorders probably have a better comb filter than the Laserdisc player?
A standard VHS deck only has composite inputs, so yes. For S-VHS it is again a question of whether the recorder's internal comb filter is a better choice than the LD filter. My expectation is the LD filter could easily be superior to an S-VHS deck filter -- the deck is designed to do a good job with S-Video inputs, composite is merely backwards compatibility.
TV's have to deal with composite from cable or antenna signals, and therefore need to do a decent job. I'm not sure the same can be said for DVD-Recorders, they will probably be more concerned with S-Video and component than composite (backwards compatibility again).
My expectation is that the best comb filters in the system are likely to be in either the LD player or the TV. Others are more likely to be purely for backwards compatibility purposes.
Depending on how serious you are, you could take the outputs from your composite sources and feed them into a high quality external dedicated comb filter. Then you would have a known quality S-Video signal for all S-Video accepting devices.
