It occurred to me today that I potentially have a good quality external comb filter sitting right in front of me. I have a 40" Sony Bravia LCD TV that somehow manages to make anything I run through it look good. I'm assuming this means it has a good comb filter and a deinterlacer at a minimum. It can output a signal from the scart connector in composite,s-video, or rgb. This means I should be able to use the tv as a comb filter and pass it on to the capture card via an s-video cable.

Can somebody point me to a list of laserdiscs that have test patterns? I have about 80-100 laserdiscs but I haven't the slightest clue which might have a test pattern that I can use to see what kind of quality the tv comb filter has.

EDIT: nevermind. It will output from the tv but it doesn't pass it through the comb filter :(.

EDIT2: I'm just going to bite the bullet and buy a better capture card. It took me a long time to find a saa713x card here in sweden but I think I finally found one. Surprisingly it's a pinnacle but it has an saa7134 chipset so I put a bid on it. We'll see in a day or two if I get it.
