Two pages on my site will illustrate my problem with JW6.
There are two audio selections on this page. With JW5, as you can see, each MP3 file gets a nice compact little player. When I "upgraded" to JW6, each file gets a video player complete with a "full screen" option. Who needs that for MP3?
The source for this page is http://hjcs.org/podgen11/feed.xml which is a podcast created by Podcast Generator (http://podcastgen.sourceforge.net/). JW5 is the only audio player I know that can play such a podcast in this manner. With JW6 I got an error saying that there is no playable file.
Why does 6 lack these basic features?
