Hi DrTurner,
Short answer is no. You can't do it within MCE and there are no plans I know of to make analog inputs on digital cards accessible within MCE.
The reason for this is because analog inputs on digital cards don't have mpeg2 hardware encoders (as analog cards do), so in order to be able to record from those inputs you'd need to implement software based encoding. Something that is very CPU intensive. It's possible to do and they may implement it one day but I wouldn't hold out waiting for it.
The best way to deal with this situation is to use webscheduler to record all your digital shows external to MCE. Record them in DVR-MS format and have them saved to the MCE "My Videos" folder and watch them later on. That way you can fastforward the ads

It's not the greatest solution but is an option. Specially of use if you have a server in the house somewhere serving content to other media centers. Put all your digital cards in the server and program it to do all the recording and just use the analog card for live tv and foxtel.
The MCE remote comes with an IR blaster that is able to send channel change events to the foxtel set-top box. So when you pick a particular channel from the foxtel guide information MCE will change the channel for you.
Cheers,
Arkay.
