Scmincev3 and Black-Rectangle, I’ve since tested video from the card, even ading a folder for Video (not created automatically, for whatever reason), and it appears to work identically to the internal flash memory. I’ll do some testing soon, to see if it’s identical with something that’s not animation.
Currently the SanDisk class 2 microSD cards are about the same price for 16GB as other cards, so there’s no reason for me to test other manufacturer’s cards, for video or anything else. Class 2 gets read at 2MB per second, class 4 at 4Mps, and class 6 at (surprise!) 6Mps. Until I can detect a difference in video speeds for internal and microSD memory, there’s no reason for me to get a higher class card.
Black-Rectangle, thanks for your comments on the ID3v2.4 tags.
I’ve edited the initial post.
