Running gtkpod 0.99.12 on Kubuntu Gutsy (7.10).

I downloaded a video podcast in .mp4 format.  I tried to add the podcast to my local "Podcast" repository but received the below message from gtkpod:

"Could not open '/home/sudawgs/Amarok Podcasts/FOX News Flash/122807_foxflash_0900.mp4' for reading, or file is not an mp4 file.  The following track could not be processed (filetype is known but analysis failed): '/home/mrmsudawgs/Amarok Podcasts/FOX News Flash/122807_foxflash_0900.mp4 '"


Under "Edit>Preference" I have the Tag Reading field as %a_%A_/%T_ %;%t.  Trust me when I say that I have no clue if this is correct for .mp4 files, .mp3 files, or any other file for that matter.  Is this tag-reading template the cause of my problem?  If so, what tag should I set up?

Thanks,

Mike
