Hi Sidari, it was on Channel 4 last Tuesday, and called "Terror at Sea: The Sinking of the Concordia"
With a title like that we gave the program little chance of being any good, but as there was nothing else on we gave it a try.
In case it's not shown again, or anyone else it interested, it is on the Channel 4 video archive at Terror at Sea: The Sinking of the Concordia - 4oD - Channel 4
