The flash audio players quits playing after about 25 minutes. If I change to html5 player it works fine except in firefox OS X where it defaults to the flash player. This occurs on several of the audios but not all of them.
If you open http://pantedmonkey.org/ with firefox using Mac OS X and listen to this week's interview and advance to about 25 minutes the audio quits, but if you use the download button it works fine. This occurs on some of the videos but not all.
I seem to have narrowed it down to not working on Firefox OS X.
