CautionESPN asked for help getting started with streaming audio to TiVo. (This was in another thread that is now closed.) I think we got stuck at the same point: creating a playlist containing one or more stream files (stations). So here's how I do this now:
1) Click left to select the Playlist folder in the left window, then right click Add Playlist. Give your New Playlist a name (I used "TiVo streams").
2) Get hold of one or more streaming "files" (really URLs). Select Web Media and a listing of stations will come up in the content window. (Also from here you can query a database of stations.) Select the speaker icon and that stream will play. Or File> Open Streaming File and enter a URL directly.
3) Alternatively, you can go to shoutcast.com for a directory of stations. Click on Tune In. This should download a .pls (playlist file), and if your file associations are set, it should open in MediaCenter.
4) Once a stream is playing, it will appear in the Playing Now view. You can play a series of stations and they will stay in Playing Now (like a history list). Select, drag, & drop the stream file(s) into your new playlist. Don't be daunted if the stream file has the name of a song rather than the station - that's a GUI "feature", and you can always rename it later.
Lather. Rinse. Repeat.
If there's an easier way to create a streaming media playlist, I'd like to hear about it
Re-start or re-share in Media Server, and soon TiVo should notice your new playlist.
