It doesn't have to transcode, but it does have to demux and then remux,
something units like the Plextor can eliminate. But, as you say, it's no
big deal except on a really underpowered machine.

But even if the process DID take 4 hours (which it shouldn't), what's
the problem? Start it when you go to bed at night and it's there when
you wake up in the morning.
