sf.tv seems to have switched to a video podcast format, which is not supported by my HTC Hero (looks like they are preparing for the iPad). Though this is stupid, it seems I need to transcode the video podcasts before I can watch it. Here some links, I will update the post later with the actual way on how to recode.

It seems, that this forum thread has a real solution.
