Bill,

if you want to come to #rivendell in irc at freenode, look for zotz. If you
would like to voice chat in a google hangout or via phone, let me know and
we can work out details.

Do you know of a good dcp video (with audio) player for linux?

I did some dcp work years ago in making a commercial for the station to run
on local theatre screens, but I don't recall if I  had a player or not
available at the time. Can VLC do it yet, I just saw something saying it
could not yet do audio and video at the same time.

all the best,

drew
