I must confess that I like this last "less is more" script way more than the long script I used before. To me, if not perfect, it's almost perfect - and, because "perfection is not of this world", I could be happy anyway!
Less certainly is more. I wish some of the studios would realise this when applying DVNR to blu-ray masters!

If there's rainbowing, then I'd give it a try. I've had limited/poor results using some of these filters in the past, and I believe if your comb filter is doing a good job then you should have minimal rainbowing already.
I used the 925 S-Video because, in my comparison tests, its comb filter resulted better than my capture card. I didn't noticed rainbowing, but you know, "four eyes are better than two"... and six are better than four etc.
So, if anyone else would like to download the OUT ruLes test clip, and let me know its problems, it will be really helpful!
I thought you were using a DVD recorder pass-through for comb filtering? I know that the s-video on my CLD-2950 is horrible compared to the composite output (which I tend to use with the "HQ Filter" off, but cannot disable it on the s-video output), I thought that was the case with most LD players, with the exception of the very best NTSC players?
With laserdiscs, after median/averaging captures, I simply use DeGrainMedian for noise reduction (and it does a nice job for the most part), Msharpen used subtly to bring back some small details, if I upscale then a combination of nnedi3_rpow2 and a Spline64 or 36 resize, depending on my needs. If there is visible colour banding then a dithering filter (like GradFun3) can help.
Today was "capture day #2"... hard work... I finished to capture all the three editions, and carefully aligned them both temporally and spatially, and then medianed... now I'm testing the script I tested yesterday on OUT
here you are the usual clip at SENDSPACE (70MB)
download it, and tell me what do you think.
Watched it and its looking good, however there is a serious misalignment of one of your captures on the first shot (look at the small moon, the Tantive's engines, then the Star Destroyer). There is also a combed frame as Threepio looks up and says "What's that?".
I'm still testing a basic color correction, as the laserdisc picture is still pinkish - but not as GKar...
Not perfect, but not too bad... (^^,)
Looks great! Its difficult with the SE because all of the transfers suffer from colour issues, you're doing a nice job.
Next days I will test the filters you suggested - if you want to help me, could you please post an example script?
I occasionally add and remove filters as needed, but those tend to do a nice enough job. Using an MT version of AviSynth helps a lot. If you have a dual core CPU then I'd try it, it should greatly increase your render speed and give that idle core something to do ;)
I use avisynthMT too - but some filters still does not improve speed with it...
I just stick with SetMTMode(2,0) at the start of a script which is maybe not as fast as manually assigning filters to threads but is enough of a performance boost. My scripts tend to be quite basic because I've found filters that I prefer and that do a good job, all of which seem to work nicely multi-threaded. I depends on the filters you are using and how much filtering you're doing, of course. As you say, some filters just can't benefit. I tend to use the default filter settings a lot of the time too, only changing settings if something doesn't look right (for fine adjustment). I rarely have scripts that occupy more than 30 lines, usually they're only about 10 lines, but then I haven't tried layering different sources! The results I get from the filters I use are very good, too. Sometimes keeping it simple is enough, I'm sure I read on another thread that the upscaling scripts for DJ and You_too's project was only a few lines...
