Has anyone with an HK 430 or 630 upgraded with the Dolby IIx upgrade package? I just got the upgrade CD today and before I do the upgrade am wondering if anyone has had any problems with the software? Thanks.

There's an upgrade available ? Cool, how did you get it ?

John-go to the HK website and find the AVR 630 product page. There's a download available there or else they can send a cd.
