Firstly, your feed's extension should be .xml or .rss, not .txt - I don't know whether Podcasts Connect will accept the .txt extension. But in any case you have numerous instances of an error, for example at the beginning:
Note that though the double quotes are the normal straight ones in the first line, in the second one two show as slanted in this reading - different applications render them differently: in Textwrangler it's an i with a circumflex, in Nisus Writer they don't show at all, and TextEdit won't even open it. This sort of thing tends to render the entire feed unreadable in some cases.
You can see all these errors flagged here:

You need to go through the text and replace all these with straight double quotes, and I should save it as XML with the correct extension.
