Download the BDA drivers from the freecom website and follow the instructions in the pdf file in the download. Then follow the instructions on the GBPVR Wiki here to define your capture source.
After I uninstall the WDM drive and then add the BDA drive. I use the config program from GB-PVR and select capture source tab -> add.
the create capture source window open, in recording source, I select BDA recording plugin.
click setting, the BDA Device Configuration window open, click 'only show devices detected in this machine', for me, only 'Freecom DVB type 5' show up in Device type. Then select suitable region and then OK.
On the capture source window, EPG source, I select 'DVB EPR Broadcast' and then click 'map digital channels to EPG channels'.
the Digital channel mapping window open, and start scanning available. After a while, I enable some of the channel available and then click ok.
