Sylah - I don't know the exact revenue from Mythbusters. But there is a note in the last annual report stating approximately 22% of revenue came from the one customer (one risk to take note of). Not quite sure who that is, but I can imagine it's some broadcasting network that buys a number of shows.
And I couldn't find the amortisation rates on television shows - but I do remember management stating they were very conservative in this regard (amortised a good deal of the capitalised amount after the season was no longer current). I have to find this again to be sure though, so don't take my word on it.
As for 7Beyond, I have no idea what impact this will have on the business. I can't imagine it'll be negative, as they'll produce the show together, with Beyond distributing it internationally. Should just mean a decent amount of content that can be distributed around the globe.
As for cash, I always like additional dividends unless they can make a decent acquisition (hopefully better than the last).
Sorry I couldn't help much with your questions...
