I did further test, the hang (lock) doesn't occur if the advertisement text file isn't in the directory. If you remain video and URL file in the same directory, no problem but if you locate video+URL+text it gets locked. Really weird.

Also, if you create an empty text file named the same as advertisement text's name, no lock occurs, but if you copy the text content into your text file that you created, again it gets lock.

Shortly, if there's no this advertisement text file in the same DIR with video, it runs OK.
