At first I noticed that either video or tv would become choippy after viewing for a few minutes even though media player doesn't exibit the same problems.

Upon further investigation I have noticed that just having mediaportal opened even on the home screen without video or music playing, after 3-5mins the cpu usage will surge to 25-35% for about 3-5mins then drop back again. I am not sure how many times this cycle repeats itself but disrupts the video at that time.

Any ideas??
