Will I have to re-buy all my HD content in 1080p?
Now that the AppleTV supports 1080p, and the iTunes Store is offering such content, what about the existing HD content that I have? I assume it's all hardcoded at 720p. Is there an upgrade plan to 1080p, or do I have to buy it all again?
Also, how can I tell whether any given HD content on the Store is 1080p or 720p? (I'm considering buying Monty Python and the Holy Grail but I will only buy it if it's 1080p; the Store doesn't say if it is or not.)
