Anyone else having problems with these boxes?I have Comcast Middletown,Ct hooked up via comcast supplied hdmi cable to a Samsung LN32a450 LCD TV.I'm about to be on my fourth box! Picked up box #3 Saturday and it was dead by Sunday night.Same thing each time,go to turn on TV or just look down at the box,no clock display.Sometimes I get lucky and the box(s) will reset after I unplug for 10-30 seconds and plug back in.But not this time.Anyone have any ideas?I like having the extra HD channels on the bedroom TV,but at this point I'll just run the coax to the TV and be happy with my 4-5 local HD's.
