Audio/Video Plugins

Hi, I would like some opinions and feedback regarding a project I am working on.
I have to build a website for a church and I am planning to use Wordpress. What I am wondering is if there are any good plugins recommendations to use that would allow the church to upload audio and video broadcasts of their weekly sermons? Preferably something that would organize the sermons well and allow a user to either listen to the audio or watch the video for that particular sermon in a pop up window so they can continue to browse the website while listening/watching. Please let me know if you have any plugins in mind that can accomplish this. Any feedback and help will be greatly appreciated!
