I've heard of it.
Seems to coinside with the time they send through the new program listings at 3 or 4am.
Could be there is something in one of your boxes not fuctioning properly, and picking up the reset signal. Sometimes equipment can cause the problem you are having, and sometimes it is something on the network side. Best bet's to call the cable company, and get a tech out there to double check your equipment wiht their gizmo's.
