You may want to hold out for a while as the dvd is supposed to be out sometime this year. You can check the software forum and do a search "clash of the titans". I have the LD and it is a rather poor transer. I think I paid $40 for mine.
I have a copy I'd sell. I seem to recall the discs as being perfect and the jacket something like an eight out of ten. I'll have to go dig it out to know for certain - my LDs are rather disorganized right now (and I have a lot of them!).
