I have a 211k with an external hard drive for DVR. I have noticed lately that when i start it up, it takes about 2 minutes for me to be able to change the channel or bring up the guide, or do anything at all. After the 2 minutes, all is well. Does it have something to do with the hard drive being hooked up? I've had the HD hooked up for about 4 months now, but just noticed the problem happening for the last couple of weeks.
