Indeed. As I've noted before, I'd personally be happy with
lowish-quality mpeg-1 for example; should be fairly light on the
decoding.

Yes, we will want to take off as many of those straws as possible, such
as doing that rotate on recode.

12fps would also probably be just enough for me, too. No reason not to
try it as long as we're talking custom-recoding for the Neo anyways, and
yes, oughta help a bunch.

Can be considered, though not having too much space on the microSD is an
issue too (if the 2G ones verifiably work, that'll be dandy...). Still,
I at least won't probably try to cram a whole lot of a/v material on the
device at any one time (as is evident from above, I'm willing to make
compromises on my video megalomania ;), so maybe.
