Multiplex operation halted on Windows XP Operating System

Hello,
I am using Windows XP Operating System but I am getting the error message saying Multiplex operation failed. I think there is a problem with video decoder. What can I do to fix this issue? Can you tell me the cause of this problem? I would be grateful to you if any suggestion will come from you as a solution. Thanks in advance.

Multiplex operation halted
Video decoder buffer underflowed 1 times.
Check c:muxman.log for details.
Resulting DVD will probably not play smoothly.
