ext2 / ext3
The ext2 or second extended filesystem is a file system for the Linux kernel, until supplanted more recently by ext3, which is almost completely compatible with ext2 and is a journaling file system, ext2 is still a better filesystem of choice for flash-based storage media (such as SD cards, and USB flash drives), since its lack of a journal minimizes the number of writes, and flash devices have a limited number of write cycles.
Most PVRs and consoles don't recognise NTFS as they use a linux based op system and therefore use ext2 and can also see FAT32 on external drives.
