I actually figured out that it was the suffix .html that was being added to the end of all my links that was causing the problem, so it is resolved. If someone wanted to keep the .html at the end though, they wouldn't be able to and have the PDF function work.
I also noticed that the same is true for those using SEF extensions like shSEF404 and ARTIO Joomla SEF. The .html must be disabled.
Great extension by the way. The only thing I would suggest improvement on is to make the frontend look to the component pages more easy to customize maybe with a GUI/Graphics preview feature. Also, I think it would be sweet to have a thumbnail of the series of a sermon/message be displayed on the frontend with the ability to customize the positioning of the download, PDF and audio/video buttons.
