[vdr] Tuning USB

Hello All,

The issue was not related to USB whatsoever - my channels.conf was the issue.

I created it with "scan" from the dvb-utils package. Turns out that
"scan -o vdr" outputs the channel frequency in kHz, where vdr expects
it in Hz. Obviously, the vdr still tunes but the recording part is
baffled.

Best regards,
      Markus
