I've been having some headaches with my cable provider, Cox, lately. I've gone through three digital tuners in as many weeks. The one I just received seems to work fine. The only problem I've found is that now I have to manually adjust the signal select from digital to analog on my Pioneer 815 receiver now. The signal will, however, automatically switch from analog to digital. I haven't changed any configurations with this new box at all, so maybe it screwed up my receiver. Is that possible? Could it somehow be the box? I get analog just fine, and digital signals. It's just a pain having to manually adjust it everytime I go from basic cable channels to digital movie channels. Any advice?
