I have had direct for two weeks now; hr34 and three hr25 receivers. Sometimes the video will pause a few seconds then play, pause again then play. It will do this until I change the channel. The audio continues to play normally when it does this. What would cause this? I am starting to get aggravated after my 4 day install; one day to install it and three days for the tech to figure out that my whole home dvr wasn't working correctly because he plugged the power inserter into a strip instead of the wall outlet.
