Hi, I am only familiar with the Book Port Plus, but if you have access to the user manual it should tell you if certain type cards are to be used with the player. A Google search should get you to the user manual if you don't have one. Sometimes it is included with firmware.

I know the thing hasn't been updated since 2009. I know that supposedly with that new firmware it can take 8 GB SD cards. But does the class 10 and ultra and stuff matter? Cause I found a 5 pack of 8 GB SD cards on Amazon but it had all that stuff to it. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus
