I have the same problem.

I have read something about we′d have to use a rss template. But i dont know how to do that.

Thanks in advance for any help

both of those feeds look fine in a feed reader – remember they are not for browsers

Thank you for your answer.
This has opened my eyes and looking to other blogs i think that mahenkpatel and me were looking for something like the way to integrate a feedburner page in our blog.

Thanks for replying, feed burner show the feeds better than before but it still doesn’t show the line breaks and images, and no matter what i select in settings “excerpt or full” it shows full post and that too without line breaks and images, which doesn’t look good, Is there any fix for that??

Thanks

Ok its weird, but as i wrote my above post the problem is solved by itself, it now shows line breaks and images perfectly, only issue is I want it to show half of the post that is till the <–more–> tag, How can i do this?

Thanks
