Thanks for all the replies. I'll try to address them all:
mnkykyd: About OSX. The only reason there is no native OSX version is because i don't have a Mac tot test it on. You could download the Linux version and try to run the episodebutler.jar. I think it will work, but I never tested it. I'm planning to make a native OSX build, but as I said, I need a mac (or someone with a mac) tot test it on.
RXP: I'm trying to make it as easily usable as possible. I'm afraid adding all kind of attributes might hurt the workings of episode butler (ie it can't find shows or finds the wrong versions). The only thing I did added was a quality selector. It's based on the three versions of an episode I come across. The low is the 400mb version, medium is the 800mb version, and high is the 1200mb version.
soudlous: See above for the info about attributes (and of course in the email I send you in response to your questions). The intervals currently are 6 hours. Every 6 hours the Episode Butler checks if new episodes are available. In the 0.5 version I'll make this part of the configuration instead of a hardcoded value.
