Did you try the softcam each time?Sorry, I disabled Tuner C and enabled B alone with a Net ID of 00008 for Nottingham with Virgin Media UK (all systems). Re-scanned ABM but no joy. I did it for Tuner C as well and disabled B but the same result.
I'm not sure the line is active.
Check inside the newcamd.list that the line is complete and it's not missing any digits 01 to 14
