I have the Avivo codes pack and I am getting an audio delay when watching videos off my HD. At first the movies are fine then as I get into them a bit there becomes a delay in the audio. The delay is about one second. To fix it I find all I need to do is pause the video, skip ahead or skip back, then return where I left off and play it again. That fixes it for about 15 minutes. Anyone know whats going on?
