Hello all,
Meanwhile I read some more on autoplugging and capfilters, but I still
can't seem to get this pipeline to work. To determine whether or not
this is a bug, could anyone using a Mac try these pipelines and report
on the results? For example, does it work under 10.4?
I also mailed with the creator of the plugin, but he wrote:

And so I did...
Thanks in advance for any input,
