I don't see any problems.
The effect is to skip the part where it toggles the lsb of the 63rd dct
coef if the sum of all dct coefs is even. (What's that for, anyway?)
Theoretically shouldn't be any worse than a idct mismatch, which is almost
always the case in mpeg1/2 because we have no idea what idct the dvd
encoder used.
