I'm preparing a new 500 GB drive to attach to a DVR1100c receiver. I want both 4 GB Time Machine and (remaining space) programmed recording capability. How should I format the drive, and where? Only in the DVR1100c? Only on a PC (with SwissKnife)? First on a PC then in the DVR1100c? Format...

Wondering why video ceased mid-morning today (July 9, 2011) and was still not working by evening. Audio is OK. We want to downlink live content later this week and need it working.
