Hi Thierry,

I have been having problems with the radio tuner in my leadtek 1800h 
card. This card has the xc2028 tuner. Using fmtools i would get an error 
message similar to - frequency out of range 0.0 - 0.0.

After seeing you patches at the beginning of last month I installed the 
recent drivers at the time and applied your patches. The frequency out 
of range error went away but the only sound I got was static. I then 
discovered the frequency is out by 2.7MHz, so if I want to listen to 
104.9 I need to tune the radio to 107.6.

On Ubuntu 10.04 the card works fine, the errors started when applying 
the recent V4L drivers that I require for another card.

Are you able to help resolve this problem and get this card working 
properly again.

Thanks

Andrew
