No problems here, really.
I do the occasional reboot and every once and awhile I get the black screen with "Please wait" on it that quickly goes away. (Which I usually follow with the reboot). My customer xp has been pretty good and though my installers have all been pretty cool, the last one screwed up a connection that I easily fixed but he left with me with tons of cable w/connectors and a couple splitters. After pricing out the cable, etc., even online, it was far, far cheaper to have them come out and do it and the materials were high quality. I think I spent $20 and got two splitters, plus an old one and enough cable to wire my neighbors house from mine if I wanted. (FYI - Cable companies generally have THE BEST splitters; usually far superior to anything you'll find at Radio Shack, etc. This came from a very reliable source and not the cable company. Who gave theirs to me for free, anyway.)
