[libdvbpsi-devel] [PATCH] Fix a parsing error in dr_02.c

[Daniel Kamil Kozar]

b_mpeg2 in dvbpsi_vstream_dr_t corresponds to what the H.222.0 refers to
as the "MPEG_1_only_flag". If the flag is not set, it means that no
extra data is contained at the end of the descriptor. The code in
dr_02.c did exactly the opposite.
