Hi, I've running on v3.00 using 4K. For the first time owning the X70, I loaded both SD card slots. I have some video on slot A, with slot B being empty and freshly formated. My problem is when I use the SLOT SELECT button it doesn't switch from A to B or B to A. The LCD shows both A & B only. Simply said, I can't switch to use one or the other independently. Any ideas? Your help would be most appreciated. Thanks, Ray

UPDATE!!
Ok..... I had the setting on "Simultaneous" recording instead of "Relay" recording. Made the change and all works as expected. Figured it out in the manual, go figure....... Somebody, slap me LOL.
