Distribution : Who is distributing on Blu-Ray/DVD? by Kenneth Barker

I am drawing to the end of post production on a retro sci-fi feature film project http://www.youtube.com/user/OTSOG2012 and would be interested to receive opinions/contacts/ideas for distribution. I have the means to self distribute and already have some interest from two UK mainstream distributors but its always nice to have additional options. Thanks KB.
