Is your solution to move all Year tags to Original Year, and then Release Time to Year?
Personally, if it was me, that's probably what I would do. If I'm changing permanently from one player to another and I'm not using the tags for other purposes (a portable player needs them, etc), it makes sense to configure my tags in a way that makes that new player display information the way I want it to out of the box.
Not saying this is the right solution for you. You may want to go the Edit->Edit Preferences->Tags(1)->Define New Tags route and enter TDRL and configure and then display it. Just saying, if it's me, the less I need to rig things up to get them work the better. That way, if I lose my settings or my drive and have to reconfigure in the future, there's less I did to have to remember and recreate. YMMV.
That said, any permanent change is a destructive move and must be considered from all angles before being executed.
