I just got HD DVR for Dish Network. The damn thing makes this whining noise when I turn it on and it just keeps on whining when I use it. I spoke to DISH and they argue that all their DVRs make noise. Its irratating and they refuse to replace it. I just had their service for one day and it's SO much louder than my TIVO that i had with DirectTV. Can anyone confirm that this noise exists on it? Thanks!!!!
