Say what?!? PCM is mandatory for DVD players, since DVDs are required to have either a PCM or DD soundtrack. Are you sure your PCM file was good? Did you try playing the PCM file on a different disc?
"So, for instance if I make three captures from three different ANH LD's and on one frame one has a rot spot and the other two don't, the output video will be without that spot. Using this method, I should be able to produce a transfer that is rid of all rot spots."
What if the "spot" is from the laserdisc material itself?

Not so sure PCM is considered to be mandatory. I used to get a lot of PCM encoded DVDs from a guy I met on eBay and they wouldn't work in my older players. One of my newer DVD Players handled the PCM audio horribly... it just kept skipping. I found that with all of my DVD Players that the XBox was the best at playing the PCM audio source.
Maybe you are right, maybe it is the encoding. All I know is that I was so glad I was not at my Grandparent's 60th Anniversary party when they tried to play the DVD I sent them and the audio kept going in and out. I don't think I could have looked in the eyes of all the people there when that happened. Luckily my brother had sent a DVD with a lot of the material I had done but with Pro-Logic (DS 2.0) sound and it worked great. He saved the day but I still felt like crap.
I think it is hit or miss with DVD Players on their level of PCM support.
Not that I think of it though, I think I should dig out some of my older players and try the TR47 set to see how that works.
PCM is raw, uncompressed audio and audiophiles just love it for music but when it comes to movies, pro-logic or Dolby Surround 2.0 will get you the same level of sound and will be much more compatible with new and legacy players.
Now you have me interested... I'm going to have to check out some pro DVDs to see if PCM is really a "default". I have ripped quite a few DVDs in my days and I am used to seeing DS 2.0 and DD 5.1 tracks but not so sure about PCM... other than music DVDs.
