It would just be nice to have a one stop source to know what theatrical or otherwise rare sound tracks can be found if one wants to sync them to a bluray or udh bluray or even webdl in some cases. 😃
The theatrical ac3 5.1 mix for starwars episode one is on its japanese laserdisc.
The original mixes for a lot of 90s/00s can be found on Cinema DTS discs such as for example for TPM mentioned above.
