>Description:

Vice 2.3 from pkgsrc-2011Q4 was built with the following default
options:

        ffmpeg lame vice-ethernet vice-fullscreen
        vice-hwscaling xaw

However, in the "save media file" menu, where FFMPEG used to be an
output option allowing to save a video, the option is no longer shown.

Interestingly, Vice itself no longer links against ffmpeg libraries
either, now attempting to load them dynamically.  However, a ktrace of
the process does show those libraries being loaded successfully.

I'm not sure yet if the problem is in the Xaw backend menu, or related
to Vice's new dynamic library loading code, but this used to work in
previous Vice versions.
