No. In addition to the post-processing option, you *also* need to set
up your Hardware Recording Profile (e.g., "Default" or whatever you
are using) to enable auto-transcode.

The idea is that some capture cards already have hardware-assist for
encoding (PVR-x50), which can be configured for your desired disk
space consumption rate at capture time. Others have no encoding
capability at all (HD-3000), so recordings made by those cards must be
post-processed by mythtranscode to save disk space. On a system with
both kinds of cards, you would only need auto-transcode for recording
profiles for the encoder-less pieces of hardware.
