Try installing the new 64-bit system in parallel with the old one, on a
separate partition. That way, you can take your time setting it up and,
only once you're sure everything is working, delete the old system. Even
if you run into glitches, you'll be able to control when the downtime
occurs -- just reboot into the old 32-bit system whenever you want to
watch something or whenever recordings are scheduled.
