Hope someone can help.  Just got an Igloo box for our living room and want to get the channels up on our bedroom tv on the next level. Brought top of the range Digitech AV Sender 5.4ghz with IR and installed last night. Getting awesome HD picture and sound, but IR not working as we cannot change channels on the bedroom tv.  Have called the shop we brought it from and have been told it may be steel in our floor blocking signal or that the remote is coded so you cannot use AV senders.  Any advice or workarounds?.  I have phoned Igloo to see if the remote is coded but they tell me they only support the installation of igloo and not av sending (as they recommend getting another box and paying for another $25 channel pack!).

Thankyou
