Looking in the engineers menu, just after euronews on 620, from 621 to 632 they are numbered as 'Test 34 hid' on 621 right up to 'Test 45 hid' on 632, hopefully this is Sky movies HD!
or
HALLMARK HD
FIVE HD
ESPN AMERICA HD
NAT GEO WILD HD
BIOGRAPHY HD
CRIME & INVESTIGATION HD
HISTORY HD
DISNEY CINEMAGIC HD
TAKE YOUR PICK!!!
I personally would like Sky movies hd as the picture on the SD channels look awful!
