Thanks for the info:
1. Cant disable remote blasters...as have a TV in bedroom and both decoders (1110 + HD PVR) sit in TV Room
2. Remote blaster is connected to the 1110 decoder only. Will check if something is wrong there.
3. Cant be glass mirrors etc...as none are near the TV + PVR
4. Remote working fine, so this cant be it.
5. HD PVR working fine, so cant be it either.
Most likely cause is your point number 2. Will check it out, thanks.
