Maybe don't subscribe to the digest, then we won't get wonky subject

That machine will "do" as a backend, but may have some problems coping
if you want to do a lot of transcoding or commercial detection. It
will do comm detection, but not as fast as you may like.

You'll probably want more storage eventually, 500G sounds a lot. It
was a lot until i started recording TV :)

Personally I run mythbuntu and simply add squeezeserver (or whatever
it is called now) from the logitech supplied software repository. My
music is in /var/lib/mythtv/music, making it available to mythtv and
to squeeze server. Works well.

You could possibly install myth on top of vortexbox, if it is based on
fedora there are good fedora mythtv rpms available from at least two
sources. (ATrpms and another i can't recall right now)
