so...if i'm on the computer that actually has the Ceton 4 tuners...why can't I record one channel and watch another which would make use of all my tuners. is this functionality not supported by Mediaportal?
you don't need to scan each, just use the "mapping" to add all channels to all 4 tuners, while your at it, double check that the recording folders and timeshift folders for all 4 tuners are set the way you want
