I would expect exactely that type of improvement - if myth is using a
transcoding program that has been optimized for 64bit.  Eventually, we
will also see a similar improvement in commercial detection
performance.

The EM64T is a strange beast in that regard.  It can do a reasonable
impersonation of a dual core chip in 32bit mode, so switching to 64bit
mode will effectively halve my processing power for certain
applications.
