MPlayer pause problem

Hi,
I encountered a little problem using MPlayer. When I press pause (space bar or P) and then press it again to resume the playback, the video jumps about two seconds forward.
In the console output I notice a change in the next to last number: in every resume it increase of about 50. In the MPlayer FAQ this number is described as “frames dropped to maintain A-V sync”.

Example output:

A:   5.0 V:   5.0 A-V:  0.000 ct:  0.000 121/121  1%  0%  0.4% 0 0 
A:   9.1 V:   9.1 A-V:  0.000 ct:  0.000 219/219  1%  0%  0.4% 51 0

Is someone experiencing the same problem?
Thanks in advance.
