the Urban trial Cahors is a once a year event and is a world level trial run under 'openfree' rules , so I'm guessing thats the motors tv one explained
as for the french WTC round, I believe france was the final round of the championship (a few weeks ago) so I think it must be a eurosport cock up. Both set to record!.
I'd recomend taking a look at Ryan Young's Advanced Trials Training DVD, taught me how to do it and also take a look at this video of cabestany, shows the amount of compression needed and the perfect weight distribution.hope this helps.
