I was under the impression that, even with CPU based encoding, the recording process went directly to the compressed format.

It doesn't have to -- it depends on the software you're using. Usually *some* kind of compression is used, though, because otherwise the disk space and disk bandwidth requirements become unwieldy. Even professional digital video systems generally use some kind of compression at every step of the process.

If you're talking specifically about MythTV, yes, there's always some form of compression. A PVR without compression wouldn't be able to record a useful amount of material.
