I own this set, and I enjoy watching it - several times a year.
This is the only way you will ever enjoy Episodes 4, 5 and 6 in full-glory Dolby Digital until Georgie-baby decides to release them on DVD. Which, at last, is several years away...
And for those of you who haven't listened to the sound from an LD - it can be magnificent, IMHO beating out DVD hands-down if done correctly. See Ep. 1 on LD... or these... or Titanic...
