It looks like you are crating new textures at OpenGL level each time.
It does not matter if you free the host textures, you are allocating all the
 time newer textures in the graphics hardware.

For movies you should use explicit texture paging. It will provide you the
maximum
performance as well as the minimum texture memory use.

If your texture is small enough you will not need double buffer the texture for
the
movie. In this case the total use of texture memory will be a single frame.

Please refer to previous postings on this mailing list regarding texture paging
on performer.

Let me know if you don't have access to the above information.

We have several people using this technique without any problems.
