It can be done but it takes some work. There are som apps like VLC that can capture a stream, or Videodownloadhelper. They still would need to be converted to a different file format in order to play them in your car. You can use media player to burn an audio CD. If your car can play MP3 file that may not be necessary. Also if you save the files to a phone or tablet you may be able to sync or hook the device up thru the AUX poor if you stereo has one.
