I am using my MCE 2005 PC as my only DVD scource and it is being a complete pain in the rectum. Every now and then the picture and sound keep freezing for about half a second and carrying on, which happens about every 5-10 seconds. And other times i get no sound at all when watching a DVD but i can listen to music in My Music. After switching it of from the case button it works perfectly for a couple of days untill it happens again. This is very annoying when you just want to sit down and watch a movie, and then have to waste 5 minuts for the bloody thing to boot up again, so dose anyone know what is causing this and a possible fix? Could it be a result of cheapo memory, as i have 1 1gb stick of unbranded memory?
