Can you add this feature by adding a playtime length column for audio and video? The reason for this is that there are site that contains many audio for podcast that does not have a file associate with the description.
Here is a site as example with a list of audio in the download list but you don't know which audio is associate with the interviewer: http://www.soullifetimes.com/soul-talk-replay-page.html
I find this extension MediaSave for Opera that display the audio playtime in order for me to find the correct audio file for that interviewer.
