HDSR or D5?

Lots of discussions today about finishing formats. Do we master onto HDSR or D5 or what? 

Essentially we need to discuss the plan for going from RED Camera - Digital Intermediate (DI) - Master Tape - 35mm film.  Obviously this is dependant on invitations to particular festivals and receiving some post funding, but the discussion has to be had.

Low budget, independant filmmakers usually only finish to a DVD which the play to their friends and maybe send to a film festival which accepts DVD's, but if you are considering a theatrical print for festivals or even screening at one of the larger film festivals then more needs to be done.

I'm no expert and the RED camera adds another equation to the mix.  Also from a sound perspective we will probably do a mix for submissions to festivals and to play from DVD and would need to do another mix should the film be lucky enough to get funding for a 35mm blow-up.
