My joy was shortlived. I managed to scan the T2-channels only once and they were loud and clear. But when I started my Vu+Duo next day, channels where not visible any more and scanning didn't spot them. The first scanning results are still listed, but they show signal 0 and no pic. However, the channel program information is visible. Sometimes it gives a message like "wrong parameters". I'm puzzled. The T-channels ar ok, signal over 80%.
