playlist plugin and absolute paths?

[mporembs]

I'm using mpd to build/manage playlists manually. It stores absolute paths in its playlist. I'm wanting to convert them to a different audio format by combining the playlist plugin and the convert plugin.

However, playlist plugin always returns empty query results. Even when given the full path of the m3u. I'm wondering if this is because of the absolute paths? I've set the "relative_to" option to "/" but it's not working. None of the other options for that config field make sense. Is it required that the paths be relative?

This is on a Freebsd server, though I don't think that matters here.
