[linux-dvb] DiB3000MC : autosearch doesn't work

Hi,

If I try to scan some transponders with the initial file [1] and the 
scan utility from dvb-apps [2], the autosearch works for the configuration
"2/3 NONE QAM64 8k 1/32 NONE" but not for the configuration
"3/4 NONE QAM64 8k 1/8 NONE".

It seems dib3000mc_autosearch_is_irq return 1 (failed), when I try to 
tune to "T 586000000 8MHz AUTO NONE QAM64 AUTO AUTO NONE".
What's the meaning of failed ?
Have you got an idea with the autosearch failed ?

Regards,

Matthieu
