I tried to use PlaylistDownloader on an old 32bit machine (Windows 7). By accident I copied 64bit ffmpeg.exe. It caused error: "ERROR: audio conversion failed: ffmpeg or avconv not found. Please install one." But that was not visible. PlaylistDownloader was stuck at 70%. No progress, no error output.
