I installed PowerISO 4.6 on my Windows 7 to load image files, such as .iso, .cue, and .bin files. However, when image file is an Audio CD, all of my players cannot find the loaded image. It says No CD in the virtual drive even if I can see the audio tracks. For data DVD, it works well. However for Audio CD, it won't work. No CD is detected after the Audio CD is loaded. I can see the Audio track. The same Audio CD I can load it using the Daemon Tool in Vista, it works just fine. My Audio CD is DTS music, by the way. Can anybody shed light on this issue? Your help will be greatly appreciated. Thanks,
