Hi everybody!

I am using Adobe Encore DVD.
When I import TXT subtitle script he give me alert message and he wrote:

"Timecode overlap found in subtitle script line:
01:00:24:06 01:00:27:08 bla bla bla."

What is the problem?
I tried two movies: Out Of Time and The Last Samurai.
In both of them, I got the alert message when the first line that open the second hour came.
I mean in both of the movies the script lines works great in the first hour
(00:00:00:00 until 00:59:99:99 ).
Could you think what the problem? Do you have this problem in the past?
Thank you for all!
