With the typical midrange dual core CPU found on a MythTV system, and
good x264 quality settings with a respectable bitrate, they're about
even. With an older chip like a P4, or even stuff like early model
Ath64s and Core2s, direct storage wins. With something like a modern SB
i7, transcoding wins. Of course the Thai flooding really threw a wrench
into the whole works, as hard drives should be down around $0.02/GB if
we had maintained the existing trends. It really comes down to how much
time it takes you to manage all that stuff, and unless you're doing this
for compatibility with some hardware decoder, its typically not worth
the effort.
