Just an update...

I have come to believe that a showcenter remote should be placed in a museum or the like, as they appear to be part of an extinct / dying species. There are none anywhere, and both UK and USA sellers refuse to send, even if you win a bid. I always ask, none volunteer.

The Harmony works, but it's a *** of a battle...may well just cut my losses and get a better more updated media box that plays newer codecs /files, and despatch the showcenter to landfill.
