I have now done so - it's 
ftp://ftp.mplayerhq.hu/MPlayer/incoming/no-sound-3gp.3gp.

I have tested it with quite a few; however I see what you mean and I 
don't think I've been able to find a mov file which has samplerate 
different from the value in the file.

However, it looks to me that it makes more sense to set nSamplesPerSec 
to the corrected value of samplerate than the value taken from mov file.
