The XSPF Playlist module finally supports Views in a more appropriate way. Previously, you could get it to display a view by passing a view name to the module. This was cumbersome and didn't handle arguments for views well. Plus somebody would sooner or later figure out how to exploit it as it was giving way to much freedom to what was being passed via URL stream.
In the ever expanding word of Media Mover modules, I finally put together a quick module that handles some of the basic configuration of the JW Flash player. Largely, this helps reduce installation time as no custom theming is required to get the flash player on the page if you're using XSPF Playlist for your content delivery.
In dealing with FLV files, it's really nice to have the meta data available for flash players and other uses of the files. Unfortunately, when you convert a file with FFmpeg, it doesn't add this data in. FLVTool2 is a Ruby tool that does exactly this. Though it requires having a running version of Ruby, it's straight forward to install.
