QuickTime does frame dropping -- you may notice a bit of jerkiness if
you look closely. In any case, as far as I know (somebody correct me if
I'm wrong) libavcodec doesn't yet have enough PowerPC optimizations to
run as well as QuickTime.... but Apple's decoder supports only a very
limited part of h.264, as was discussed elsewhere in this thread.
By the way, please include a blank line between quoted text and your
response. You did in the part immediately below, but not elsewhere.

- the problem is my fault
