From what info i receive it seems the firmware have DVB/Guide/ locked for the specific targeted market
My BD D-6900 don't have this problem with FIRURDEUC-1006 firmware so when i look into decrypted firmware i found 5 folders containing DVB and DVS settings for tuners:
SESK_T2C
SESK_T2C_NORDIG
SESK_TC
SESK_TC_ASIA
SESK_S
Each folder contain :FineTune_Digital ,map-AirD,map-CableA,map-CableD,map-AirA,map-ChKey,LNBSettingsDataBase.dat and ServiceProviders files
Strange but looks like the files exported by TV/BD on USB when you backup channel settings (or clone TV to usb in SM)
Could be possible to modify channel table/frequencies/symbol rate inside backup with "channel editor"and import back to device ?
Anyone ?
Solution: Go to service menu and change "REGION" from PANEURO to NORDIG or viceversa and EPG /clock will work ok
