This has gone on way to often. The MYSTRO system, as I understand it, was introduced to increase the bandwidth and availability of HD channels, but the system, to put it mildly, SUCKS. There is constant re-booting, the time for the system to respond is 10 times longer than the old system and if you don't have a DVR box, then the system is dreadful. I literally can count to 10 before the channels will change. It is dreadful. Tomorrow I'm calling DIRECT TV to check out and see when would be the earliest that I can switch over. Time Warner Cable....YOU SUCK!
