I've seen these warnings too. But most DVD players I've used in the  
past worst case maybe pause the video for one or two frames before  
resuming. With xine and mplayer I really have to be looking for the  
layer switch to find it. With the Internal player it's very obvious.

Happens also with ISO files ripped with MythTV.

Yes, they seem to. If a caption is on the screen when the layer  
switch hits then that caption is "stuck" on the screen until I skip  
back a few seconds and/or toggle captions on and off.

I was thinking it might be helpful for me to find a few popular disks  
and make a note exactly at the time code I see the problem. This way  
others can test and see if they can replicate. Anyone have  
suggestions on popular DVDs I should try?
