FWIW, I found this on the Laser Guru site:
Q:"I was hoping you could educate me a bit on PAL laserdiscs.
Was there a THX widescreen release of the original SW Trilogy in PAL, similar to the "faces" set here in the US? Or alternately the CAV Definitive Collection?
If so, what LD players can handle PAL format discs? Only those built for the UK/etc market, or is this latent capability present in US players (assuming you have a display that could handle the PAL output)? I have seen models like the D515, or CLD-959 that claim to do both NTSC and PAL. If US players can't do it, what UK model would be equivalent in PQ to at least a D703/704?"
A:" There were some PAL laserdisc releases for the Star Wars movies , including a Special Edition box set. Sadly, no Definitive Collection or "Faces" editions......
To play a PAL laserdisc, you need a European-model laserdisc player. Such a player will only output the signal as raw PAL, and will not convert to NTSC. US-model LD players will not recognize or play a PAL disc at all.
Unfortunately, the PAL laserdisc market was miniscule, even in comparison to the tiny US market for LDs. Even the best PAL laserdisc players only approach the quality of our mid-level models such as the CLD-D606. The discs themselves tended to be poorly mastered, often converted from NTSC video transfers. Even with the few extra lines of resolution that PAL affords, it is rare to find a PAL laserdisc that looks as good as its NTSC counterpart. As a rule, it's not worth the effort for someone in the US to acquire PAL laserdisc equipment."
