title: Windows 7 Beta and Invalid MCI device ID. Use
body: <p>Not certain if this will get much response due to the newness of Windows 7 and its beta release, but here goes...</p>
  
  <p>Some caveats;</p>
  
  <p>1). I have not torn into my code yet</p>
  
  <p>2). The app works great in Vista and below</p>
  
  <p>3). Uses MMSystem for multimedai playing of mp3 and cds.</p>
  
  <p>I have an application that plays music CDs (cda) and mp3s that works great in Windows Vista and below, XP, 2000 etc.</p>
  
  <p>When run on Windows 7 Beta, I get... Invalid MCI device ID. Use the ID returned when operating the MCI device when initializing the player.</p>
  
  <p>Is this part of a bug in Windows 7 Beta and its media player or the main focus of my question, does/has anyone else experienced this and found a simple solution before I tear into my code?</p>
  
  <p>Thanks!</p>
