Abu, thanks for the replies.
Firstly I've only used my net ID in abm 40965
Q1 ABM functions on vix 5.2 025 fine except im not getting bt sport 2, all other bouquets fine
If I do software update to 026 abm will not scan, shows failed to scan tuner B
Q2 When abm succeeds, yes can see the channels and yes I can select the channel
No error on screen, just blank for a few seconds then shows a still pic of the previous channel I was on
739 Mhz 6952 Quam256-3/4 snr 0%
Hope this answers your questions, many thanks
