I have the same problem using regular Philips LCD TV remote. I was trying to save all the alternating key sequences I was suprised that there are no 2 alternat keys but 6 in one direction ?!

Never the less the main problem is that flirc is somehow mixing the keys as for instance when I press left it is sometimes acting as right or return. As I am new flirc user I have never tried older firmwares before. I am open to downgrade FW and try that again where I can donwload the older FW ?
