I have just uploaded my LingQ activity video on YouTube. Have a look.
I opened the lesson and listened to the audio with external audio player. My browser FireFox3.5.2 on Windows XP links to this audio player. When I clicked audio download icon, this external audio player popped up and play the audio. It repeats the part A to B and I can change the audio speed easily.
This audio player is named BunBun-Hayaemon and it’s Japanese free software. I don’t know it works or not on non-Japanese Windows.
