I'm also wanting to know this.

If I play it back through the player - the sound is fine. If I convert it to AVI through the player, the quality of the video goes right down, and the sound is stripped out completly.

Is there anything else that will play these files?

I would also like to know the answer to this.

If i play them back through the player, they are fine, however if I convert them using the AVI button, the video quality is drastically reduced, and the sound is stripped from the video.
