Hmm, the translation layer doesn't work correctly. It doesn't
translate new bandwidth value 1 to old bandwidth value 0,
although there exists code to do this translation, and it should
get called as the other translations happen correctly.
As a result the old driver uses a bandwidth of 7 MHz instead of 8
MHz.
While copying the code here to ask for help in searching the bug,
it seems that I found the bug -- a missing break in the DVB-T
case ;-)
Please try the attached patch.
Bye.
