Got my hands on a THX 1138 Bluray from a friend (Bought it from him) and he let me rip it with his computer (He has a bluray drive) and i might try dabbling with despecializing. Though i do have to wait as he is ripping it and i will get it in a week.
Edit: Does anyone have some info on original individual scene colors (For accurate color correction) or any other info? Or even a rip from a good source? That would really help! Thanks.
