Hi,

Some time ago I did dvbscan uk-Bilsdale  with my Avermedia DVB-T USB-2.0.
The result was of the form:-

ITV1:474000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_1_2:QAM_64:TRANSMISSION_MODE_2K:GUARD_INTERVAL_1
_32:HIERARCHY_NONE:513:651:8275
ITV2:474000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_1_2:QAM_64:TRANSMISSION_MODE_2K:GUARD_INTERVAL_1
_32:HIERARCHY_NONE:2824:2825:8339
ITV3:474000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_1_2:QAM_64:TRANSMISSION_MODE_2K:GUARD_INTERVAL_1
_32:HIERARCHY_NONE:2950:2851:8310

Using zap or xine I can get the BBC channels but no others. 

At present
# dvbscan uk-Bilsdale appears not to work and gives:-

Done.

This suggests the  tuner is not working and yet it still allows me to get the 
BBC channels. The antenna I am using is presumably not the problem since I 
can get all DVB channels using it on the TV set.

I can get no help from Avermedia who say they do not support Linux. Any 
suggestions will be welcome.
