I think there is a bug:

        int64_t iPagePts  = (int64_t) (Data[ 9] & 0x0E) << 29 ;
        iPagePts |= (int64_t)  Data[ 10]         << 22 ;
        iPagePts |= (int64_t) (Data[ 11] & 0xFE) << 14 ;
        iPagePts |= (int64_t)  Data[ 12]         <<  7 ;
        iPagePts |= (int64_t) (Data[ 13] & 0xFE) >>  1 ;
        fprintf(stderr, "video pts = %lld\n",iPagePts);

It should be:

        int64_t iPagePts  = (int64_t) (Data[ 9] & 0x0E) << 29 ;
        iPagePts |= (int64_t)  Data[ 10]         << 22 ;
        iPagePts |= (int64_t) (Data[ 11] & 0xFE) << 15 ;
        iPagePts |= (int64_t)  Data[ 12]         <<  7 ;
        iPagePts |= (int64_t) (Data[ 13] & 0xFE) >>  1 ;
        fprintf(stderr, "video pts = %lld\n",iPagePts);

Doesn't explain the difference you're seeing, though.

Hm...
