The syntax "0:p:" want a program ID, which is "1" in your case
(reported as "Program 1"). The option suffix is the stream *index*,
which would be "2" again. So you could use "0:p:1:2" instead of "0:2"
(since you have only one program in your input).

No wonder, I see only stream IDs 0x20d, 0x69, 0x2b in your input, no
0x378. So you may have wanted to specify: "0:i:0x2b". ("It works for
me.(tm)").
