I think it's not limitation of filesystem but DOS and programs which works with files (in case of mplayer the libc functions for seeking and reading - what data types it use). There's a patch for windows 98 that allows work with 4GB files in standard way. I tried it only on FAT32 partition not on FAT16 and it works well. So I think it shouldn't be impossible under DOS too (AFAIK DJGPP use 32bit signed pointer for files so it would be needed to extend it to 64bit and also probably FreeDOS would need some patch).

DOS gives me freedom to unlimited HW access.
