Forgot to say that with this patch the Astrometa DVB-T/T2/C usb stick 
now has working DVB-C reception at all the frequencies I have at home. 
Before it was not working at around 290-314 MHz.

The current status of the Astrometa stick is that DVB-T and DVB-C (8MHz 
tested, 6MHz testers wanted) should be working fine. DVB-T2 needs 
working pid filters before it can work properly.
