as the official releases [4,5,6] will be possibly be a few years away, you have 2 options.firstly try your luck with the many dvd versions you find. bear in mind they are only copies of the laserdisc version! i don,t own the dvd versions ,and would be more inclined to get the laserdisc[ntsc], even if you don,t have a laserdisc player., you can pick a cheap player up nowadays.secondly i think the laserdisc is an investment. thirdly i have read the dvd,s don,t output proper 5.1, and the dts is not even present[if these dvd,s are just copies of the laserdisc, did the laserdisc only have 5.1?...don,t recall dts!] the choice at the end of the day is yours.......lastly , if your tempted by the laserdisc, the PAL version is only dolby pro logic,,,,,the NTSC version is 5.1! hope this helps.
