Hi,

I've spent several hours lately trying to work out why my dvd.iso file 
was not playing correctly in ogle, thinking it was a bug in my dvd.xml 
that I was feeding to dvdauthor.  Now having installed totem, I believe 
it to be a bug in ogle.


In ogle-0.9.2-r1 from Gentoo Portage:

When playing titleset 1 title 2, upon returning to the menu at the end 
of the video the buttons are completely invisible in ogle, although they 
work when you click in the appropriate empty space.  Pressing 'r' makes 
the buttons appear.  Titleset 1 titles 1 and 3 do not exhibit this 
issue, ie, when returning to the menu at the end of the video everything 
appears as it should be.


In totem-1.2.1 from Gentoo Portage:

Menus work without any problem.


Attached is my dvd.xml, in case that sheds any light on the matter, if 
you need me to debug I'll be happy to help, if you provide instructions.


Claude
