Since this thread has now served it's purpose, I'm going to close it up but before I do I'd just like to pass on Shameless' thanks to everyone who responded.
As Marc mentioned, Shameless
have decided to go with seamless branching. However, what Marc didn't mention was that Shameless hadn't even considered this idea before it was mentioned on here and got such a huge amount of support.
The opinion of Cult Labs members is very important to Shameless and it's because of you guys that they have decided to go to the extra expense of having seamless branching on the DVD and Blu-ray.
Thanks for your comments!
