I don't think Emerson actually manufactures anything anymore. If you do a Google search you can see that they're part of Redmond Group of Companies (RGC) which includes TDK, Sandisk, Koss and others.
I'd be more curious to know who the actual manufacturer of the dvd recorder is. (Edit: The Emerson EWR10D5 is made by Funai).
