I am having a bit of trouble understanding your post. It discusses Karaoke Home Producer, and apparently Microstudio also. It appears that KHPro is working fine as you can import, synchronize, export and the created file can be written to a CDG disc on another system.
Have you done or verified all the Microstudio Thread suggestions in the
http://www.mtu.com/vbulletin/forumdi...&daysprune=100 Forum? That is the first place to start to diagnose a Microstudio/CDR drive problem.
Are you running Microstudio 2.200?
Can you take a karaoke cdg disc and make a duplicate in the Duplicate Disc Tab, or read in individual tracks using the Custom Assembly Tab and then play them?
Check your video card especially. There have been several problems directly related to this card and the Windows settigs for it. You can run a "Search" on "video card" or "display card" in the Microstudio Open Forum to see some of the posts made in answer to these problems. Open and read each Thread that appears for the search and try the suggestions.
