I have placed a question in the Toast support group but no one wants to 
touch it.
Here it is:
  When I play back my last DVD Music album it has a problem I haven't 
encountered before.
Let's say I am playing one sonata. The DVD player on my computer shows 
which sonata is playing.
When that sonata is finished the next one starts playing - BUT the 
text/button has NOT been switched to the name of the new sonata - Then 
a few seconds later the music stops completely, the next button/name of 
the following piece appears - and then the music resumes. Any idea?
I could live with the button/name of song out of sink, but the music 
stoppage for a few seconds, no way.
By the way, I have tried the same DVD on the DVD player attached to the 
TV and the problem remains.
TIA
