On some channels audio standard automatic detection just doesn't work.

Sometimes microcontroller hangs for 10-15 seconds in "detecting" state, then
detects correct standard (A2-DK1 in my case), sometimes it detects AM-L
standard which produces GSM-mobile-phone-like noise, sometimes it detects
nothing at all. There are no visible problems with signal quality on any of
affected channels, clean and clear picture.

So the question is, is there any user-configurable ways to disable automatic
detection and force audio standard to some fixed value? Looking at source code
in input_change() function, audio standard is forcefully set for some hardware
bug affected PVR150's, otherwise its always set to AUTO..
