The latest updates of the DVB-HD module should be performed with caution and only if necessary.
I'm using several DVB-HD modules with BV 7-40 (MKIV) and BV 6-26 with MEDIAGUARD ASTONCRYPT PCMCIA smartcards and the cable operator's card. Everything worked fine until I did several updates of the modules (now 0.1.7.1.0), which resulted in the smartcard not being recognized anymore. This is surprising since the ASTONCRYPT smartcard is recommended by B&O for this purpose.
In short, all my DVB-HD modules are now useless with this smartcard, the only one which is compatible with my cable operator (except the POWER CAM PRO, but it is no longer sold).
Did anyone have a similar problem after the DVB-HD module upgrade... which is rather a downgrade!
