if you have channels with numbers in the 800s it can cause recordings to fail because you will be getting e.g. bbc1 signals from two transmitters and the dtr gets confused. have had this problem and [because its auto tuning only, with no manual option] only solved it by doing a rescan on a 'bad reception' day, when the tuner fails to pick up the transmitter on the weaker frequency. if anyone knows a better way I'd love to hear it.
