Looking for an iPad(iPad/Mac) app that allows for playlists to migrate to iPad

I am specifially and exclusively looking for recommendations for an iPad(iPad/Mac) app that allows for my playlists to be migrated to iPad intact and playable.

iTunes -> Podcast/Music/Videos does not support mixed (music/video/podcast) playlits or video playlist at all. The app(s) should be able to easily create these playlist on the Mac (and manage content) much like iTunes (10).

On the phone with tech support today and they agree this is missing functionality from Apple. They suggested I reach out on to other users that may have a thrid party solution.
