After reading almost all articles about the stuttering (TV, DVD, HD) problem the last few days. I finally solved my "problem". I found out that a Graphic card utility (ASUS) called "Smartdoctor"was causing the stutter (every few seconds). It was monitoring every 5 second the graphic card for (heating?) problems. It was running in the background at system start. After disabling the utility the stutter was gone.
I hope this will help some of you.
