i have just downloaded the latest SVN build (12 June) installed, activated my trailers and hey presto, went to Fantastic Four RotSS and 2 trailers were availble to watch.
Thanks to Ronilse and Dukus for sorting this out.
Still doesn't work for me. Even downloaded the new RC1 to see and still no dice. Just says "Error. Unable to play selected videos". It does at least list the trailers now though
on a side note...is there a way to use ffdshow (or any other way to make them look better) on trailers? Some of them look like total poo on a 60+ inch screen.
