Hi Julian

Plugins work out what files to process based on their file extension. I
would expect pptplug to process all files ending in .ppt.
Depending on what you have set the process_exp for UnknownPlug to be
(.mov ?) it will handle all files matching that expression. or are you
using process_extension (mov)?

A possible explanation is that some of your powerpoint files cannot be
processed by pptplug, and are getting passed down the plugin pipeline.
And their filenames happen to match the process_exp that you have used
for unknownplug.

I suggest you try some/all of the following to work out what is going on:

put gli into expert mode (file->preferences->mode) and rebuild to see if
you get any errors.
remove unknownplug temporarily, rebuild and see what happens to your
powerpoint files.

you may need to modify your process_exp option to unknownplug to
restrict it to mov files.
If you are using process_extension mov and it is processing ppt files,
then there must be something wrong with our code.

Regards,
Katherine
