I have been extensively testing this release on native mode Jooomla 1.5 RC4 and later nightlies, it is stable, easy to use and can easily be styled to fit in with your site template.
Its main features:
Works with J! 1.5 Native mode
Extensive database use for regularly used items such as the names of preachers, series titles, topics, bible books and media file locations. Also stores size and duration information.
Multiple media handled for the same study (text and mp3 and video for example with different icons for each)
component table can be styled for background colour\text size etc from the back-end
Module that shows most recent studies\talks again with plenty of configurable information elements and style tags.
Component view that has configurable drop down menus to easily find a certain series or speaker and also full text search.
Limitations - Its a back-end component so there no front-end editing, you will need to upload your media seperately and manually enter the duration and size information. At the moment it doesn't include podcasting functionality but that is in the pipeline for the next version.
Support from the developer has been second to none and plans for future releases sound very promising.
A great component that does so much more than it's humble title suggests.
