personally i have found this forum to be great. But try DVXuser.com It caters to Panasonic DVX100 users but it is a very good filmmaker forum. You dont need a dvx to join. It i one of the biggest filmmaking forums on the net. DVXuser combined with this site you should be able to find any answer to any question.

"Anyone who has ever been privileged to direct a film also knows that, although it can be like trying to write 'War and Peace' in a bumper car in an amusement park, when you finally get it right, there are not many joys in life that can equal the feeling." - Stanley Kubrick

I'm pretty new here, but this seems retty swish. Also, I've been involved in setting up a new part of an existing forum for film makers... not many people on it as of yet, but hopefully it'll only get better! It's: http://sjcultmovies1.proboards23.com/index.cgi (under the film maker's forums, obviously.) At the moment most of the stuff on there's related to events and people in the UK, but the people who post obviously are the ones to make or break a forum!
