Try this:

local tap = Listener.new("ip","mp2t")

but it will enter to function tap.packet(pinfo,tvb) every IP packet not every TS packet as i would expect, correct?

Well I haven't tried it, since I don't have a capture file handy with TS packets and non-TS packets, but in theory it should only call tap.packet() for packets matching the filter in that second argument to Listener.new(), and thus only MPEG2 TS packets.

I have tested and it does not work as expected. I can send you capture if you want.

Yes please send it - or put it up on cloudshark, or attach it to a new bugzilla ticket (https://bugs.wireshark.org/bugzilla/)
