Steve,
YES!
I upgraded to Windows 7 Ultimate, and the playlist now works as expected. I first tried VideoBox with the standard setting, but that didn't solve the issue. I installed the English language pack, and changed location to US. Now when I play 1 song (or more), the finished songs no longer show in the playlist, and when done, I can start with a fresh playlist.
The error message on start up still shows, but doesn't have an effect on the program. (I think....)
It is a bit strange so you may want tolook into this a bit deeper with your engineers.
A last suggestion: Add to the wishlist an extra time indicator for the complete playlist. I am planning to use a coin selector, and don't want to have customers putting in coins when the complete playlist plays for say 50 minutes !
Thanks for your support, and I might be back with other questions.
Wim.
