a way for "time" to appear on itunes

[micimpact]

Hi,

I have read all the previous questions answering that SmartCast does
not support the episode duration time to appear and that I cannot
modify the FeedBurner feed to add the duration.

So my question is, is there a way for me to have the time appear in
itunes in any other way?


I am currently hosting on blip.tv.
The url on itunes is http://itunes.apple.com/us/podcast/ceongcungominsangdamso/id516903991?ign-mpt=uo%3D4

and the feed url is
http://blip.tv/micimpacttv/rss

It would great if I could get some alternatives.

Cheers
