> In dvb_demux.c, some logics exist which compare the expected
> continuity counter and the real continuity counter. If they
> are not matched each other, both of the expected continuity
> counter and the real continuity counter should be printed.
> But there exists a bug that the expected continuity counter
> is not correctly printed. The expected continuity counter is
> replaced with the real countinuity counter + 1 so that
> the epected continuity counter is not correclty printed.
> This is wrong. This bug is fixed.
