RC5 is a very common IR protocol, but device 19 is not.  It's best to get a OEM remote.  However, you can program most universal remotes made by UEI (e.g. OneForAll) with the 994 command, using the following EFCs.  You'll need a remote with setup codes  Audio 1089, 1189, 1269, or 1289.  Or TV  0855, 1154, or 1931.  Video 1731 will also work.
