The MXOFF is basically an escape sequence that is used to escape the huffman tables, basicallly it reads a single bit from the bitstream and jumps through an array to a new address. The problem is that one of the tables includes a jump >255 so they used the case of Jump > 250 (0xfa) as an escape sequence to make this possible.
AFAIK this is only generated for one entry in the huffman table, so if you identify it you can go in and manually change the addresses and remove this little test for a not insignificant performance gain. The only table that uses it is table 24, if you read the huffman decoder algorithm and play around with the numbers in the table you can make a valid table without too much tweaking.
