For those who want their digital copy. I've checked both discs and could see no sign of any video files other than the VOBs etc.
I have unfortunately found my disc to have some authoring errors - I tried to select the 'Select Cartoon' option and my UK PS3 froze. I've had a bit of trouble getting the full disc to play on my laptop (With a Samsung External BD Drive) and it took an extremely long time to load. When I selected 'Select Cartoon' it moves to the correct menu screen, but it displays with lots of corruption.
The main movie appears to be fine, however.
It's a shame, and I'm loath to mention it because of the nature of Thunderbean's operation, but you may need to be aware of whether the disc will play properly on your player before purchase.
