PSNR Drop at every I frame.

Dear all,
 
i m using 1.0beta2 version of theora encoder for my production work.
 
i have encoded one QVGA stream at 300kbps stream with the following configuration.
 
sharpness---------------------------0
noise_sensitivity------------------6
keyframe_frequency-------------64.
 
same stream has been decoded using theora decoder.
 
PSNR has been calculated for the decoded stream but the value of PSNR is dropping drastically at each 64th frame.
 
can anybody please let me know why this is happening like this.
 
Regards,
Nallam.
