On 5W you'll find the well known Italian DVB-T2 multiplexes. They are transmitted via DVB-S2 ACM/MIS. Each Inputstream carries a complete DVB-T2 mux.
But there's also a different method to distribute the signals to DVB-T transmitters via sat or other links. The programmes are encapsulated in T2-MI transport streams.
ETSI TS 102 773, Digital Video Broadcasting (DV
; Modulator Interface (T2-MI) for a second generation digital terrestrial television broadcasting system (DVB-T2)
T2-MI can contain a single or a plurality of muxes in physical layer pipes. The problem is that a normal receiver will see T2-MI as pure data transmission. Only after the the stream is decapsulated the video and audio streams can be decoded. Luckily there is tool available:
4T2 Content Analyzer -> hxxp://www.4t2.eu/4T2ContentAnalyser.html
But this is not enough. In addition to T2-MI the transponder 11513V, 30000, 8PSK, 3/4 uses ACM/MIS. The Italian mux is in Multistream (1)
Apparently there are more T2-MI transmissions via satellite, that I can't receive. E.g.: at 39E is a Turkish mux on 11667H which can be received by "normal" DVB-S2 cards, No MIS
but you'll need a big dish in western Europe 
Here are 2 screen shots. They show T2-MI before and after decapsulation. The latter is from a file because te 4T2 Content Analyser has a lousy direct show filter implementation.
