Hi, Since he's on a mac, he can read any FAT32, NTFS or HPFS. He just can't edit reliably directly from it. I use Tuxera NTFS to read and write NTFS but can't edit from it.
On the other end, I'm a straight kind of guy. So... I'll put my 2 cents here: He just don't want to touch your video, I wouldn't, from what I understand. Yet it remain to be seen :-)
