I think it'll be plenty awesome on a BD25 disc.. besides, the 50GB blanks are still kind of steep in price.
Looking forward to burning a few for some fine folks :)
..as for the audio, I'm cool with what I though was already decided by Hairy_Hen - DTS lossless with DD 5.1, as well as boatloads of others. Personally, I leave it all "as is" and don't bother taking extras out. Doesn't bug me to keep 'em.
On another topic - anyone have any luck authoring any tests with the "making of" clip? Just curious if there's been any progress on authoring, as that seemed like a pain last we were all talking about it.
