Has anyone had major problems with their receivers over the past few years? I've had DirecTV for 3+ years now and I've replaced all 3 original receivers. The last to fail was an H20 replaced with an H23 that has already started acting up. I don't know, it seems like these receivers are just cheap Chinese junk. The receiver in my office (H21 I believe) reboots itself every 1-2 days. The new H23 has rebooted itself at least twice in 4 days and when I came home today there were no programs in the guide, only "current programming" or whatever the default message is. The receiver in my bedroom is the most reliable but it, and the others, routinely give error messages that guide data has not been received for X hours. I've checked all the signal strength, wires, b-band converters, zinwell switch, etc and its all fine. IMO these receivers are poorly made garbage from China but maybe that is just my bad luck?
