WordPress MU

I installed iPodcatter on my Wordpress mu, but whenever i try to publish a post with an iTunes:keywords tag and a duration tag it gives me this error message.

WordPress database error: [You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE meta_key = 'itunes:explicit' AND post_id = '17'' at line 1]

I haven't tried ipodcatter on Mu, and it's of limited use anyways. If you can't get it working you can always just register your sitewide feed or any individual blog feed with Feedburner as a podcast feed then register that with the iTunes store.

I too am trying to get iTunes type meta data into my podcast mp3 on my wpmu blog. I am using Feedburner as you suggest, however the only item that does not appear is "duration". My Wordpress enclosure shows the length in bytes, which is stated in the RSS xml this way:
enclosure url="http://feeds.feedburner.com/~r/Welstech/~5/221690814/welstech-podcast-1-23-08.mp3" length="40002548" type="audio/mpeg"

However, I need it to be part of the iTunes tag like this...

iTunes example: itunes:duration 7:04 within itunes item tags

Without this, my "Time" on iTunes is blank.

How can I tell my Wordpress post the new duration time for each podcast episode?

Feedburner's Smartcast does not give me this item option. I am using the AMP Anarchos media player plugin - which does not have this option either.

Any ideas?
Thanks!

I think some people have had success with podpress.
