With an MC plug-in I am sure we will be able to get even more functionality.
Just to make sure there's no confusion...
First, a definition: "Learn": Allowing an application to respond to your specific remote events. Not all remotes send the same code for a particular keypress... so any application needs to learn which codes are sent by your remote for each keypress.
JRiver is talking about adding a plugin to MC that allows you to "learn" the remote from within MC. This is a very nice feature for out-of-the-box use, as it's pretty darned simple.
If you want the most functionality possible with your remote, I suggest you use Girder. It will control almost every facet of MC (much more than you can do with "learn") and that's just the tip of the iceberg. If you search INTERACT, you will find reference to Girder configuration files that are already "learned" for MC. Setup for Girder is Easy to Hard. depending on who you ask. But there are plenty of us here on INTERACT that have done it, and the Girder forum has *tons* of help available.
