my dtoshiba vr works fine with ariza..but is there a way to control the channel change from dvr so that timer recordings automatically go to the particular channel on ariza 700 and record. I have IR cable with the receiver and it does not have codes for fta receivers. I need recording with no manual input ..it automatically records ch 140 (espn) for example every day at a specific time.. at present i need to manually make sure my ariza channel is set to 140 for thist
