Greetings, fellows. I'm a long time reader, first time poster. I own the original TR47 set and enjoy reading about the technicalities of laserdisc transfers. I wanted to throw an idea out that pertains to one of the bigger problems with doing laserdisc transfers- low resolution and aliasing artifacts. I imagine some of you have heard of DCDI technology by the Faroudja company. They put motion adaptive scaling chips in displays and in DVD players that intelligently eliminate interlacing and "jagged edge" artifacts. If one was to pass the output from a laserdisc through a display with DCDI and then somehow output the resulting signal to a capture card, would that gain a significant advantage over simply applying various "anti-alias" filters to an already lower-resolution signal as has been done already? I say this because the laserdisc transfer I have seen seems to double up on aliasing flicker- there are interlace/jagged artifacts from the laserdisc source and additional interlace artifacts from the DVD encoding. It can be downright distracting. Hypothetically, I would think somehow harnessing this advanced de-interlacer chip would yield a more refined and smooth picture than we've seen before. There is a decent explanation of this algorithm near the bottom of this page: DCDI I know most Sharp LCD screens make use of this chip, for instance.

Let me know if I'm crazy or maybe onto something. Aside, I'm in awe of all the hard work being done here. Thank you!
