Just to be clear:  I'm talking about file size limit, not
volume size limit.  All FAT versions up to (and including)
FAT32 store the file size in an unsigned 32 bit integer,
so the maximum is 4 GB - 1 byte.  However, a single HDTV
recording can easily exceed 4 GB, so FAT is unsuitable for
that purpose.
