iTunes alternative doubleTwist has been updated with podcast support.

doubleTwist users can now subscribe to podcasts, search for new shows and  sync those podcasts to a variety of media players.

Other updates:

• library sorting issues fixed (sort by original track number)
• id3 tag discovery and display enhancement — not a full featured id3 tag editor but progress has been made on a more stable display of id3 tag info from iTunes and WMP media.
• Support for networked drives added
• Status and progress of application loading (status of iTunes, WMP scanning, playlists importing)
• ability to reload iTunes and/or WMP playlists at each launch
• Ability to not scan iTunes for changes at each launch
