no problem with that, it's the gnome session manager that refuses to let
the gnome app connect to it (different user owning the session manager?)

colorspace depends on libhermes. If you install this library the
colorspace element should compile.

This usually means a connection between two pads failed. In your case
I'm betting on the fact that your X server doesn't support Xv images
(you need at least XFree 4.0 for that) and there is no plugin
(colorspace) to perform the conversion in software.

quicktime only supports a few codecs ATM so I wouldn't be surprised it
failed.

Can you try again with libhermes installed?
