Hang on!
I've just checked their web site.
The French/International signal on Astra 19.2E is to be encrypted (from the 1st Feb) with MediaGuard 2.
Their signal on Hotbird 6 (Europe) is already encrypted with Viaaccess 2.
However, there is no mention of Astra 28.2E (which hosts most 'Sky Digital' channels). Also note that the evil Sky 'Digiboxes' only understand free-to-air or NDS-VideoGuard-encrypted signals.
Dare I say it... but it's still free-to-air with a 'Sky' setup.
I honestly expected MotorsTV to encrypt on 28.2E, and that I'd have to adjust my dish to 19.2E for free-to-air. However, it seems to have gone the other way!
