Even with the filter cleaned, it will not show me the files that are there 
in the directory.  It will show dirnames, but no files.

I am not building it, this is the version 0.7.8 from the pclos 2010 + pass 
repo's.

Not at all Dan.  And I assume that others have been able to make it work if 
their distro supports libraw1394-2.00 or newer.  pclos in this regard is a 
bit behind the time at version 1.3.0 & everything else is built against 
that.  The current dvgrab-3.2 or 3.5 as I just built it, is helplessly 
looking for /dev/raw1394, and of course isn't finding it.  kino-1.3.4 
appears to be self-contained and that works.

Good, I'll take a look after dinner maybe.  I just promised the missus we'd 
go out for dinner. I hope she feels like it anyway, COPD is slowly taking 
her away.

Some of those scripts were for qdvdauthor, so I also installed that and the 
rest of its dependencies.

I'll be back with some sort of a report, I need to get this done. 
(hopefully while they are still married)
