I have had the premiere 4 for almost a year and have started to experience reboots and stuttering during recording playback. I have the 4 year warranty from best buy. Does anyone have experience getting them to swap you out at the store? I called and they told me they need to have it for a week to look into fixing it. I sarcastically asked if they were going to sit in front of it for a few hours to make sure but seriously how would they know its fixed? Think I could get them to swap me for a Roamio on the spot? If they offered me the lowest model do you think I could come up with the difference to upgrade to the plus?
