its a file for A Receiver called "BVB Max". you can use this updates if you have the box offcourse and the card " Omnia with ATR **********C1***** to get CSAT 19,2 East.
Think your right think it opens the Key08 info card on XXL/Dorcel during the day but nightime does not open as current key09 not on card (ie thought it was only Key08 channels that were still working on it unlike the Funcard Canal Sat Key08/09 file in the Funcard section which has Key08 and Key09 channels).
But I will have to test tonight....
So your prob right as Mine's an Original Omnia 1 (so I guess depends if you have Omnia 1, 2 or 3 and which file you have on it also!!!):
at the moment channels are open, but i think this is because key08 is in use. when switching to key09 at night it will be go black, because there is no file available with actual key09 inside.
