Same here! I know where to enter the duration in the XML file, but FeedBurner wont let me edit it manually.
- Here's the code if you have your own XML file:
Include the file length in bytes with each episode enclosure item:
<enclosure url="
http://www.yourhost.com/episode1.mp3"
length="25209836" type="audio/mpeg" />
(you probably need to get the bytes info from the audio file properties)
Please advice if anyone knows whether I can manually edit FeedBurner XML
