Apparently you have enabled the line

//#define WAIT_FOR_TUNER_LOCK

in device.c. By default this line is not active, so if you haven't
enabled it yourself (in which case you shouldn't be surprised by
the behavior) I wonder which patch did so? If a patch activates
this line, I strongly recommend the patch author refrains from
doing so!
