I have a Loewe Xelos A22 LCD. I am only able to perform basic funtions with a Sky remote such as turning the tv on and off, muting and changing channels with the numerical keys. I cannot alter the volume or change tv channels with the up and down keys. I have tried all the loewe codes with no success. Sky say that as it is a new tv, they do not yet have a working code. I am thinking of getting a Loewe RC1 or RC2. Would this solve my problem of being able to control my tv and set top box with one remote?
