Is there any way to add more tuner(s) to that setup?
Can the CAM decode more than one channel at one time?
Or can the CAM be used in 'playback' mode - so you record encrypted mpeg to HD and then run it through the CAM when you play it back? (I assume this is how Sky+ works)

Hmm I'll have a root around the avforums, if people can view those channels and/or the HD ones, with similar Windows setups then it should be fine for us too.

Is the current BBC HD channel on Sky FTA, encrypted as FTV or encrypted along with the normal 'Sky package' channels?
Thats odd that Sky broadcast the BBC's HD channel in DVB-S but their own in DVB-S2!
I assume that the BBC one will move to DVB-S2 at some point...

Thats promising. Is this using standard mplayer and the ffmpeg codecs that come with it?
What format is the BBC stream you tested? 1080i/720p/1080p?

I've read that the Core H.264 codec (Win32, non-free) is multithreaded so hopefully the the ffmpeg one can go that way too. But 40% is fine... my current frontend is a Celeron500 :-)

takes a CoreDuo and might make a nice quiet HD front-end...
