Tom-
On the copy of Vertical Ascent I got the music AND sled sounds feature didn't work. I had to chose one or the other. I think when I chose the music and sled feature I just got sled sounds. It really makes no difference to me and I loved the video but thought I would mention it to ya in case this maybe something is wrong with other copys. There's a chance I'm just to stupid to work the DVD player but I'm pretty sure I had it right. Anyways, great video, I can't wait to get the new one!
First I've heard of any issues. All you have to do is hit the audio/language button on your dvd remote and it cycles threw the 3 available audio tracks. Maybe try it again and PM me the results
