I downloaded the 3cd DTS version of A Tale of Two Sisters some time ago, but had an awfull time getting it to play. Looked around in many forums and although some falsly claimed that it could be played through a normal ac3 codec, almost everyone said that there was no codec for it. Well there is! It was damn hard getting it though, cause I had to go to some Corean site and find the link through looking at the source.
Anyway, I upped it to my own site so that should anyone else ever need it, you'll have an easier time:

Now the installation is also in Corean, but it isn't really that difficult understanding which buttons to press...
