I wouldn't count on Sony to create device profiles. However, all the data that is saved for your remote, is saved in text files. Which means it could be possible someone would write a program to download device profiles. Or perhaps they would redesign the entire program, to add what Sony didn't include.

Sadly, older technology is phased out even though it is working completely fine. This happens with computers all the time.

It is a good remote once you get it to work. I think even a different newer remote might have problems with older systems.

I have a LaserDisc Player too. I have not yet tried it with my AX4000. I hope it works.
