Good afternoon!

Long story very short, I was one of the lucky ones to grow up with LD in the '80s. As with many, I lost touch with it as newer tech emerged. Thanks to my dad, and his impressive collection of players and discs, I have been reunited and have quickly fallen down the rabbit hole.

I have a Pioneer CLD-2080 piped through a Pioneer VXS-D703S to an RCA 22" CRT. The setup works well enough; the PQ is good and the stereo sound is great. However ...

I want to watch my growing LD collection on my Visio E601iA3. After connecting the player via composite, and hooking up the audio via optical cable to my Sony HTCT660, I was devastated by the PQ. The stereo remained quite good, though not as impressive as through the Pioneer receiver.

After reading many articles here (my favorite being How are your newer tvs not analog doing playing laserdiscs?), my question is as follows:

What's more important ... de-interlacing for a progressive picture or investing in a very good comb filter to fix the composite signal? My LCD has a pathetic 2D filter.

Thanks for your time and thoughts!

A good DVD recorder will do both, as well as scale, which is also important.

Yep, I've seen that solution and I'm on the lookout for one that is not too pricy.

Follow-up question, and I may be off the mark here, but: If the video signal is de-interlaced, doesn't that negate the need for the comb filter? Does the filter do something more than compensate for drift?

Thanks again.

I would imagine the video goes through a filter first before getting deinterlaced. When I had DVDO deinterlacer, it only had a 2D comb filter so it was better to use the S-Video out from my then CLD-R7G (which had a 3D comb filter) to connect to the deinterlacer. Otherwise, the deinterlacer just works with what it's fed. It doesn't split the composite video's luma and chroma signals.

De-interlacing and Y/C separation are two very different processes.

Chroma and Luma separation has always been required for an LD (or any) composite signal, de-interlacing converts the interlaced signal to a progressive one for modern displays.
