Okay, I did what you said and then right clicked on the cd (heaven on earth) and then clicked on Properties and this is what it said:
Under the General Tab
Free Space 661MB
Total Size 680MB
Under the Auto Play Tab
Select a content type then choose an action for Windows to perform automatically when that type is used in this device and there's a drop down box with these choices:
Music files
Pictures
Video Files
Mixed content
Music cd
The "music files" was the choice that it was already set on and that is what played the video but not the music.
And, btw, I have Windows XP if you need to know that.
