B&O DVB T/C tuner model 0.8.0.0 software 0.1.7.1 in a BV8-40 is showing the wrong polarity after autotune from the local transmitter. As a consequence reception is poor with sound and picture drop-out. Tried a manual tune but same result. Is there a way to manually input the correct polarity? No aerial problems and have tried other boxes on the feed and no such faults ocurr.

Thanks for any help
