when playing divx or xvid files now the picture hangs after a while but the sound keeps going fine.

it's not my set up as it should easily play these files and used to up until last week. I've checked the properties when playing and it's doing 12fps at best and then slowly goes down until the picture freezes.

we had a friend over last week who was playing some films and i suspect they've changed something and not told me..(can't get hold of them at the moment)

any obvious suggestions? tried defragging the drive but still no better.
