One or more files could not be added to a compilation.

The following files may not reside in the VIDEO_TS directory of a DVD-Video compilation. Only compliant DVD-Video files
VIDEO_TS.IFO,
VIDEO_TS.VOB,
VIDEO_TS.BUP,
VTS_nn_0.IFO,
VTS_nn_0.VOB,
VTS_nn_0.BUP and
VTS_nn_m.VOB
can be added to the VIDEO_TS folder. Please add files from a completed DVD-Video title or use an authoring software like Nero Vision to create DVD-Video files from standard video files such as *.avi and *.mpg.


si quelqu'un sais qu'elle est le probleme merci de bien vouloir m'aider ...
