Im in an Rv with pay as you go plan, my trav’ler is blocked by trees so broke out the Tailgater pro, coax straight to reciever, im only on one sat,,,61.5, and if im recording i cant change channel unless i stop recording even though both channels are on same sat, i go to Diagnosticsscreen and click on tuner and it only shows #1, so is this the way the tailgater works, i thought if i was on same sat i could watch and record a different channel, thnks for any info
