How do laser disc's look on plasma TV?

I have a Japanese 919 myself and it is just a so-so LD player. If you want the best available player made for the US market, go with a Pioneer Elite CLD-97, Pioneer CLD-D704, or Mcintosh MLD-7020 which is the same as the Elite. There are a few more that are good such as some of the Thetas or EADs but the are based on the best Pioneer transports. I have a Japanese HLD-X9 which is the best LD player made. It is also playes Hi Def Muse LDs.

Laserdisc players don't have component outs. Unless of course they are combi players and the LD portion still will not use the component outs. LD players differ greatly in quality as well as laserdiscs. The newest discs are very close to DVD without the digital compression and the sound is often better as well. The sound is analog. DTS discs are very few but usually of higher quality. LDs were just really getting good when DVD came out.

None of the best ones play both formats in fact the X9 only plays LDs, no CDs. I borrowed this info about the digital sound of LDs.
(Unlike DVDs, which carry Dolby Digital audio in digital form, Laserdiscs store Dolby Digital in a frequency modulated form within a track normally used for analog audio. Extracting Dolby Digital from a Laserdisc required a player equipped with a special "AC-3 RF" output and an external demodulator in addition to an AC-3 decoder. The demodulator was necessary to convert the 2.88 MHz modulated AC-3 information on the disc and convert it into a 384 kbit/s signal that the decoder could understand. DTS audio took the place of the PCM audio tracks, and required only a direct connection via Optical Audio cable and a decoder to be heard.)
