"Cant Parse Feed"

Your first URL isn't a properly constructed feed at all. The second is nearer to it, having the 'iTunes declaration' at the top. However there are numerous errors: please see this FeedValidator report. Looking at the line numbers there:

Line 14: this tag should contain an 'itunes:email' tag with your contact address. You may be able to omit this.

Lines 17 and 19: You must stick to the categories listed here.

Line 20: this is OK, FeedValidator doesn't know about this new tag.

Line 26: the 'length' attribute must be the file size in bytes. The media file URL is OK (FeedValidator doesn't like https but it's in fact recommended). Your filename has spaces in it, and though the feed has correctly handled this by substituting the code %20 it's better not to have them in the first place: however it isn't actually a problem. Incidentally your file starts with an 8 second pause and this isn't a good idea.

Line 33: you can ignore this the 'atom' link, but you should have an 'itunes:explicit' tag set to 'no' unless you have strong or sexual language in which case it must be set to 'yes' for each affected episode and the whole podcast.

Although a couple of validators pass the feed, examining it in PageSpinner shows that in some cases you have an odd character in place of the normal line return:

This operates as a line return in most readers including TextEdit, but it's an invisible character which shouldn't be there. In two cases in this extract it's inside a tag. I don't know exactly how this has arisen, but it's likely to be the problem. This sort of thing can happen if you construct your feed in a word processor - these can insert invisible characters.

Incidentally Podbase reports that your image is 1024 x 1024 px - this will get you rejected: the minimum is 1400 x 1400.

Your media file filenames have spaces in them: the feed correctly substitutes the code %20 for each space, so it's not a problem, but it's not good practice as spaces aren't allowed in a URL.
