Now I've got my devices built and installed I get exactly the same - I am 
trying to use scan to get as far as finding channels - and scan reports 
tuning failure.

alan at roo:~$ scan -a

alan at roo:~$          


(my devices are id:14aa,0225 and the firmware is dvb-usb-wt220u-fc03.fw)

Someone of the mythtv mailing list suggested I edit the scan file to change 
the 505833333 to 506000000 and it improves the situation slightly

alan at roo:~$ scan uk-CrystalPalace

It is probably relevent that syslog is full of this
