I've only had a quick look at this, but I'm not sure if this is right.

According to http://kernelbook.sourceforge.net/videobook.pdf :

"VIDEO_TUNER_LOW  The tuner frequency is scaled in 1/16th of a KHz steps. If
not it is in 1/16th of a MHz steps."

So since we're setting a value in Hz, and LOW set means 'KHz' and LOW not set
means 'MHz', we should multiply by 1000 if the flag is not set and by 1 if the
flag is set (the 1000 for the KHz are already contained in the initial
multiplier 1/16 * 1000 = 0.0626 * 1000 = 62.5).

Does this make sense? (I don't have hardware at hand to test right now)

Could you provide more details about your hardware/driver?

Maybe you could provide a GST_DEBUG=*v4l*:5 log of what's happening and the
corresponding code?
