aujourdhui.tv -> sounds good, but correct is aujourd'hui, which shows how complex french is... How would the french people type in this kind of address?
But a good point is that .info and .biz are held by a parisian newspaper...
chiens.tv -> sorry, no idea about this...
bijouterie.tv -> this could be a homeshopping channel dedicated to... hum... bijoux (jewels)
boxe.tv -> "sport"+.tv is always nice IMHO, but so as I told you before, I don't think that french speaking people type in "naturally" a term + an extension (even a .com) so much as english or german speaking people...
They only go on well established websites and most of french people don't have a good opinion of domaining, and parked pages

where in other countries it is well tolerated. The best example to show you the french point of view regarding the domaining, is the restrictions to reg a .fr...
modeles.tv -> no idea... ah yes, just one, to be correct, you will also need the IDN version: modรจles.tv... but this is another story
acht.tv -> I watch frequently german television, but there's no mention of a channel called acht or a 8th channel, so sorry, I don't really see a value in this name, but I could be wrong: I think I remember that you get nice traffic and clicks
alkohol.tv -> I like it... it is good that all other main tlds are taken but unfortunately, no one is developped.
