Playing large movie files on an external hard drive with the PS3

[SBrooks1]

Here's my problem: I've got some WMV files of HD movies that are 8+ GB in size. Apparently the PS3 will only read a external hard drive if it's formatted with FAT32. The only problem with FAT32 is it won't read any files larger than 4GB which makes my WMV files useless.

I tried formatting it to HFS+ (Apple's file structure) and it works perfectly on my 360. But I want to use my PS3 as my main and only media player, not my 360.

So what other file structure will the PS3 read from an external hard drive that can handle files 8+GB being on there? FAT32 can't so what else is there?
