Hi All, I am using an AMD Quad core system. When playback an audio CD using WMP, I some times will have some 'red cross' in front of the sound track if I click the "Next" button. It happens on all the audio CDs I tested so far, but if I use a virtual CD ROM to playback the CD content extracted from the disk, or use an MP3 CD, the issue will not happen. And I am using an onboard audio device with 7.1 speaker config with 48K sample rate, it is not likely to be a load issue, as least it does not seem like it.. The issue is not with my DVD ROM either, because I have the same issue with an external DVD ROM as well. I am wondering if there is any flag or anything to enable WMP to print out some debug message so that I can have more details of why WMP fails to open the new stream when the "Next" button is clicked? Thank you. Angela
