Thanks for those ideas – I will check it out and see what I can come up with.
If it becomes too hard I might have to resort to Blu-ray as the theatre can offer this system at the moment.
I guess a home burnt Blu-ray is probably just as stable as a post production house one off burn as the process is, I imagine, the same. The pity of it all is that my home burnt Blu-rays look superb projected on my home cinema system, but my lounge wont fit 400 people!!
Thanks for the input
