I did add a 5th changer to my setup recently. Found a DVP-CX985V on Craigslist from someone local here in Maryland for $150. Couldn't pass it up. With only 70 slots left in my 4th changer I figured I might as well get it over with an add the additional changer.

While I won't be updating my TSU7500 PCF for the 5th changer I did update my TSU9600 XCF. Below is a shot of the "Direct Changer Access (DCA)" page from my TSU9600 XCF file.



Came in quite handy having 5 firm keys below the screen. To browse backward if needed I just hit up the power button or activity based icon in the top left corner, both of which I use as home buttons and at times for browsing backwards.
