Burning DVD with Yosemite 10.10.2 with New Photos 1.0

Since I update to Yosemite 10.10.2 with New Photo 1.0 I can no longer burn DVD. I been using Dawn Ark 1 DVD Pro 3.1 with the OS X 10.9.5 and I Photos 9.5.1 that was burning the DVD with no problem.

Now the system is going thru all the steps - that the burning is completed and kicks out the disk - however there are not visible files on the disk. I open the disk files and there is anything on it. I am following the same steps from the OS X 10.9.5 system. Any help on the above.
