drjdan, I ran with one feed on my 942 for a few months before I could get the second line run. Like SimpleSimon says, run the 2nd line and save yourself lots of grief.
Having said that, the tips for running a single-line 942 are available via search. I can't remember everything I did to get it to work on mine. Dual-TV mode, for one, and setting the prefered timer to the Sat1 instead of Sat2. Also, disable the nightly reboot. You'll still need to be prepared to sit through the switch set-up screen many times, and you'll need to manually download the EPG.
