I commited the changes now. Playing dvds (from /dev/rdisk1) still crashes in
NextDataPacket.

Looks like p_bit_stream->p_data->p_next would point to nowhere (but it's not
NULL). When p_bit_stream->p_data becomes p_bit_stream->p_data->p_next (on
line 134 in input_ext-dec.c), p_bit_stream->p_data is invalid,
which leads to a crash in the while-loop condition
(p_bit_stream->p_data->p_payload_start ==
p_bit_stream->p_data->p_payload_end).

At have no idea why p_data->p_next is bogus - Could someone with more
background on the decoder structure give me a hand?
