Sound stops for 0,5 - 1 seconds.

been looking as some normal Xvid .avi files here now.
First i thought it was something wrong with the movies, but after testing several of them both on the computer and on the PS3 and the problem only shows when i use the PS3, like once every 10 - 20 minute the sound stops for 0,5 - 1 seconds or so.

using:
windows XP.
PSM v.1.10.51
Gbit lan
