I have a new HR21 that about once a week will just get a gray screen. For example: Everything will be normal... I'll change the channel and the screen turns gray the blue info screen comes up like normal but then it goes away and it stays gray. For fun I went into the menu screen and told it to do a sat signal check where it then proceeds to just sit at the menu screen like its brain dead. A reset of course cures the problem but this is annoying because it happens about once a week and recordings will either be gray or just not there at all. Should I try a reformat or just call support and off course they will tell me to reset it and it will work and they will tell me its fixed and the annoyance will continue... My other HR21 works great and I have a HR20 on the same sat dish so I know its not the sat.
