Funky feed issues

[churk]

There's something weird going on with my feed that I can't figure out and I don't know the right things to search for to see if it's already been discussed, so apologies in advance if this is a totally bone-headed newbie obvious type question.

I recently moved my files over to libsyn and burned a feed with Feedburner and now things have gone weird.
* Here at Podcast alley my show is listed and all episodes are there, but the filesize shows as 0.
* iTunes still lists me but says my shows aren't playable episodes.
* I got Odeo pointing to the right feed but now none of my shows are showing and updating won't pick them up.
* Feedburner's validator says "length attribute of enclosure must be a positive integer" and "type attribute of enclosure must be a valid MIME type" on the original feed, and the same on the Feedburner feed, plus warnings that the iTunes summary and subtitles shouldn't contain HTML -- which they don't.

Something's obviously wrong with my feed, but I'm completely stumped. Can someone please take a peek at my setup and tell me what's going wrong and suggest how I can fix it? I'd sure appreciate it.

The podcast is No Soap Radio at http://www.deadpan.net/nosoap.
The original feed is at http://www.deadpan.net/nosoap/?feed=rss2
The Feedburner feed is at http://feeds.feedburner.com/nosoap
My Podcast Alley listing is at http://www.podcastalley.com/podcast_details.php?pod_id=10424
For what it's worth, the libsyn feed is at: http://nosoap.libsyn.com/rss

Well that sort of worked ... almost. I did what you suggested on the two latest entries -- 10 & 11, which happen to be the ones I've done since the move -- and the original feed validated that far down. But then as soon as it got to #9 and earlier, the same problem is presenting even after I go in and make the edits you suggested.

Update: it's all straightened out. Your original solution is what did it, ferf. What happened was that on epsides 1-8, I somehow missed a quote mark at the end of the filename line when I went back and did your suggested edits, and that one quotation mark screwed the whole pooch. When I figured it out and went back to fix the others, that fixed everything. So now my PCA listing is right and and my iTunes subscriptions are exploding! So thanks, ferf, you da man.
