Never tried myself, but if you have to play something that previously 
played at 1/23.98sec in 1/25sec, then you have to either:

1) keep the wave data unmodified but force a sampling rate of 
OriginalSampleRate * 25 / 23.98

2) resample the wave to OriginalSampleRate * 23.98 / 25 AND play it at 
the original sampling rate.

At least that's the theory. Don't know if this can help.
