Tim -

Agreed on all points. The only reason for RAW support is so I don't
have to drag out the JPG and essentially create duplicates of
everything just to view pictures on my Myth box. In slideshow mode,
one would have just enough time to unpack a RAW file and get it ready
to crossfade in. Having duplicates of everything just makes my life
more cluttered :).

Not a big deal. Just a pipe dream. :)
