I've just watched Season 5 on DVD from Love Film - thought it must be the end but I see there's a season 6 already airing. Can't wait for that set of DVDs as I don't have Sky or Living or whatever you need to watch it in the UK.
For cable (which I have) it is channel 7 abc That depends on where you live, have cable or satellite reception. Where I live its channel 7 in Ireland (north and south) its on rte1 and in the UK its on living (sky)
There is STILL no offical release date (which is ridiculous considering season 7 has now finished over here)...I'd recommend buying it from the French amazon site. That's what I did, just change the language to English and it plays exactly as it does on TV :)
