Not only can you record video, but you can record audio from the radio too. This is useful for people like me who like to record a series and "binge listen". When you view the recordings from a remote machine on the network you'll find that the videos you've recorded have a .ts extension (MPEG transport stream) and the radio recordings have .mp3 extension. However the audio isn't in a mp3 container they are merely .ts files given an .mp3 extension.
Why does this matter? A transport stream can contain lots of other stuff that you don't want and consequently the files are quite large. However, you can use VLC to convert a .ts file to an .mp3 file and I found that this typically shrunk the size to a tenth, thus saving disk space so I can save more files for my future binge listening.
