Does the radio mode of tRio work with bare MP2 streams ?

I need to play the MP2 streams that my DAB digital radio software outputs. I have sucessfully streamed these streams to my receiver before, using one of the other client replacements.

I know the streams don't have all the Shoutcast stuff in them. Here is what happens when I try to play one of these streams (I don't hear any sound):

Opening station content url: ST1, conn: sun.net.www.protocol.http.HttpURLConnection:http://po.norman
.cx:9000/pls/49700.pls
Opened station content url: ST1, method: GET, header fields: {Connection=[close], null=[HTTP/1.0 200
OK], Server=[WinDAB/1.0.2], Content-Type=[audio/scpls]}
got header: [playlist]
got header: File1=http://:9000/mp2/49700.mp2
got header: Title1=WinDAB
got header: NumberOfEntries=1
got header: Version=2
Shoutcast read length less than 0 bytes. Looping: 2
PlayerStream (/212.135.232.141) - sent Purge(). dataLen: 0
Updating config file
PlayerStream () - stopStream()
PlayerStream () - stopStream()
PlayerStream () - stopStream()

I also tried streaming direct from the MP2 stream instead of the playlist:

PlayerStream (/212.135.232.141) - streamStart()
Opening station content url: ST2, conn: sun.net.www.protocol.http.HttpURLConnection:http://po.norman
.cx:9000/mp2/49700.mp2

While messing about hitting, play, fast forward, stop etc I did briefly hear a fraction of a second of audio from the direct MP2 version.
