In principle, I agree with option 6 as well.  Mike's question hints at
my single question regarding the topic though: does option 6 (first
one) mean that pretty much everyone must have video acceleration
hardware (or else a fairly powerful CPU)?  Or can the thousands of
users that currently use mpeg-2 encoders and have standard-def analog
TVs likely continue with their current hardware (assuming their
current hardware handles the heavier themes in 0.23)?
