n00b wants to play movie to quicktime over net

[Peter Maersk-Moller]

Hi Randy.

Not so many Randy Bush in the world :)

Read some of the mails, but a bit confused what you are trying to do. Do
you want to decode on your remote machine and transmit raw video over the
SSH connection back to your OS X platform (XV wont work, but imagesink
will, if setup correctly) or do you want to transmit encoded video from
your remote server to your (probably) laptop ?

Can you send a link to the clip you want to play/display?

Best regards
Peter Maersk-Moller (old Ebone)
