The latest firmware has been know to cause issues, hence the recommendation to stick to 078 FW.
I havent had any problems at all with the remote, all I can say is the remote is only as good as the user. Takes patience setting it up but works a treat once done and set up as properly, too many people seem to dive in and do anything and everything at once, but with a remote like this is worth being patient and doing things in a logical process. After all this isnt your regular remote.
