I'll begin with the usual advanced apologies if this is a duplicate post. (If so, I couldn't find it) My H23 receiver is changing channels by itself, in a strange way. While one program is on, say channel 301 (Nick Jr), it will switch to something that might be on HBO or something. If you press info on the remote, it still thinks it is on 301, only no program description or title. If I change channels at this point, it goes black, into la la land for a bit, then will come back to the living and act normally again. The problem is random, but has happened at night around 9-10 PM CST on channel 301 each time, around 5 times. I have tried a hard reset (unplugged the power, etc), and it has happened again. When this happens, parental controls do not work, so our 4 yr old had a big education experience the other night with some foul language. I called Directv, they said they had others call about it, the engineers were working on it. In the meantime, the receiver is now unplugged, and I will be calling until I hear it is fixed. What a mess! Anyone else here experience this ?
