BOAC…. I had the same problem (too many different remotes), so I purchased a universal remote control from the local Sainsbury’s. It cost just over £9.00 it is reasonably simple to programme, the auto-scanning process is a little time consuming, but it came with a booklet containing the codes for most devices. It’s quite compact and now happily controls TV, DVD, Freeview box and audio unit (doesn’t stop it getting lost down the side of the sofa though).
Before you spend vast amounts of dosh on some other high-tech gizmo, take a look at the cheaper options.
