Thanks for the input on Riven guys. It is true that there are two versions: CD and DVD. We have received both from the publisher. The problem with the DVD version is that it uses VOB format for movies. CD version uses Cyan's format which is much more reliable since it does not rely on external format.

So, while releasing the DVD version might increase (negligently) the quality of the FMV's, it may also cause a flood of tickets in our support department ;)
