I borrowed an af9015 device some time ago, and the owner told me that 
the primary problem with it is that it has no hardware PID filter. So 
even if VDR is only doing EPG scanning, the complete multiplex is 
congesting the USB link. Maybe your Fujitsu-Siemens receiver has a 
hardware PID filter...
