The encrypted one is used by Sky Germany, and is encrypted with a version of NDS3 so that one at least is unlikely to ever be able to work with MythTV.

Oh and almost forgot:

The bitrates vary but 25 to 35Mbps is common for actual events and the demo loops. Testing occurs at anything from 15Mbps to 40Mbps with massively varying encoding styles.

ffmpeg has been able to decode all these transmissions for about 18 months, at least one of the other open source PVR projects can record the transmissions.
