Easiest way to do this is when the show comes on hit the record button, then select tv2, then down to options, to recurring timer, and then new episodes only and exit out after that. The show will record on tv 2 side of the reciever freeing up your side.
The other option is to hit the dvr menue key, select my recordings, select schedule, select timers, select manual, select dvr, select mon - fri, select the channel, then select create timer, and then select the start time and end time and be sure to set am/pm.
