external hard drive and PS3

so first off im new to this forum. also im not too savvy with mac but im learning. but heres my question. i have an external hard drive that i would like to put movies on. i want to be able to take that hard drive and plug it into my PS3 and watch the movies. so how do i format the hard drive to work both with my mac and ps3? if there is even a way. please help. thanks.

I'm not sure which file format the PS3 needs. However, to start I would format the hard drive as FAT-32 to see if that will work. FAT-32 is compatible with your Mac for reading and writing. Make sure though when you format the hard drive with Disk Utility that you choose "MBR" and not "GUID".

Here is a link to the PS3 online user's guide page about supported video formats. It has the most up-to-date information.

As for the format of the hard drive, use MS-DOS (FAT). That will allow it to play nicely with your PS3 and Mac.
