Hello,

We have a performer app (loosely built upon perfly) in which we use the
movielibrary to play some QuickTimes on surfaces. Technically this works
- we use mvReadFrames and then pfTexImage to apply each frame.

But then there is the problem. Usually when we get close to the
movie-textured poly it gets erratic - showing a frame, then an
untextured gray polygon, then textured. When we back out it shows
smoothly again. (the gray is not an unfilled image buffer, we make sure
to zero it to black before each fill)

This is on an Onyx2 IR IRIX 6.4.1, 512MB RAM, 2x64MB RM boards,
Performer 2.2.

We are doing the updates in the app process.

If some guidance or code samples exist for doing this (is it a sync
issue between texture update and draw process?) properly it would be
greatly appreciated.

Thank for any help in advance!
