Video module don't find the video file with FileField Paths module

After saving the node for the first time I have this error:

Could not display the flash because sites/default/files/xxx.mp4  does not appear to exist

But the files is in "sites/default/files/video/4/xxx.mp4" because is set the directory path to "video/[nid]" on the FileField Path settings.

If I edit the node and save it again without changing any things the video is displayed without problem.

I don't use automatic encoding but encode the video in the right format on my desktop.
