I have took another look at your blog. This time with my Firefox browser which has an active NoScript AddOn. By default all scripts getting blocked. But it is possible to allow single elements like the XSPF Flash player.
I have loaded the blog and allowed only the XSPF player to appear and the result was/is that the player plays all your episodes without problems. There is one issue: the playlist looks like in my blog. It seems that the player needs some further Javascript to retrieve the other information from the files. But that issue is probably explained by the restrictive script blocker.
Since the NoScript blocks for instance scripts of your blog, it blocks also script errors and that is the important thing. It seems very likely that if you can resolve the Javascript errors of your blog than the player will work again.
I have just noticed, that you are working on the code :) . no errors anymore on the Home page and the player is working.
Any advice on how to adjust this would be greatly appreciated.
This effect should be go a way when you clear the cache memory of your browser and you reload the page.
During your tests you have inserted the line of code with the URL of the gallerific library and the comment characters /* */ into the footer. That is probably okay. But these kind of comment characters do not work for HTML tags like <script>. You should remove them (BTW: they are visible at the bottom of your blog pages).
On the category pages and the pages with a single post one JS error still occurs.
Fehler: $("#thumbs ul.thumbs li").opacityrollover is not a function

If removing the comment characters does not help then you should place the line in the header of these pages. Maybe it is important that this library is loaded at an earlier point in time during the page load.
Since this error still exists on certain pages and the XSPF player is not longer visible on these pages, it is hard to say whether the player would work on these pages or not.
Is the WP-Member Invites plugin active again?
Does this certain error occur while the WP-Members plugin is deactivated?
