USB disk format (post Mac format) compatibility with Sony bdp-s370 blu ray player

[usbhelpplease]

I've used my usb key to play movies on my sony blu ray player many times before.

Now that I formatted the disk on my mac, I started to get a message that said the usb is not recognized. After searching around, I found possible answers, but none worked. I formatted the disk to FAT 32, but still got the same message. I tried making it into ntfs-3g format, but still nothing.

Has anyone had this problem or know how I can format it so that I can play videos again on my blu ray player?

Thank you!!!

Change the partition table to Master Boot.
