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.

Hi does anyone here yet have the M311? 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.
