Video as Backgdrop Texture update and Memory usage issues

Duno if it is a bug but if i shuffle through video as backdrop image the memory usage grows and if not using reload to free the memory (workaround?:confused:) it crashes.

Second problem is that a video as UV-Texture doesnt updates with frame shange, only if i use reload.

Using 2.49a on 32 Bit XP in both cases.
