Got some really great help from mm1352000 to look at my system and the conclusion was that the bda hack wrecked my system Going to reinstall tonight and install firedtv drivers and tvserver first thing.
- WHS2011 do support BDA devices from fresh install, and MePo TVserver works as a charm on that system. Had a small scare, but setting 1 channel per CAM fired up the system
- Do check if there already is firewire on the motherboard before trying to install ancient PCI firewire card no supported by 64-bit OS. This started everything.
- MePo forum members are great people
