Dvd Problem

i have a powerpoint dvd player and my prob is that when i place a dvd in it whether its new or old one after about 10 minutes the DVD will pause ever so slightly till about the first hour is up which is quite annoying then it runs normal after that ,

has anyone got any clues?

Get a better DVD player.

If you have the player long it may just need a clean - try a HMV DVD Lens cleaner.
