OpenSceneGraph is one of the open source 3d engines, people have experimented with videotextures with it
There is a tutorial for playing back video in OpenGL at NeHe
depending on the architecture, should not be too difficult with many of the engines. we used them first in PixelShox some years ago, and since them they have been implemented in e.g. ogre, crystalspace etc. i believe.
