I'll post the original v1.1 DVD soon, with the official 1.2 & 1.3 patches, and the unofficial 1.4.3 patch. Also I didn't find any proof that there was ever a 1.2 Retail DVD, that was probably a fan-made (the files on the DVD are unpacked, so it's a matter of replacing a few files). Also, the internet says that v1.2 was very disbalanced gameplay-wise, so it's better to have the v1.1 and patches, so that you can switch between version whenever you want to.
P.S. While playtesting I didn't find any way to play the vob videos in-game, only the original low res videos.
