Problema con visualizzazione video

[-Bruno90-]

ciao a tutti.
nella mia applicazione vorrei poter vedere un video (meglio la preview) appena registrato lanciando l'activity MediaStore.ACTION_VIDEO_CAPTURE
ora, la registrazione del video non dà problemi in quanto il video lo salvo e riesco a vederlo entrando in video.
Del video ho a disposizione l'uri che mi viene settato con l'istruzione:

Codice (Java): [Seleziona]

videoUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);quando utilizzo una VideoView mi esce l'alert "impossibile riprodurre il video".
appena premo il pulsante salva l'app esegue:

Codice (Java): [Seleziona]

if (requestCode == VIDEO_CAPTURE) {
                    if (resultCode == RESULT_OK) {
                        //use imageUri here to access the image
                        video.setVideoURI(videoUri);
                        video.setMediaController(new MediaController(this));
                        video.requestFocus();
                        ETLat.setText(""+videoUri);
                    } else if (resultCode == RESULT_CANCELED) {
                        Toast.makeText(this, "Video was not taken", Toast.LENGTH_SHORT);
                    } else {
                        Toast.makeText(this, "Video was not taken", Toast.LENGTH_SHORT);
                    }
                }
e il logcat:

Ho provato con il codice delle ApiDemos di google la VideoView_Demo, modificandolo settando
mVideoView.setVideoURI(videoUri);
ed estraendo l'uri desiderato da un db esterno.
Anche in questo caso l'app nn riesce ad eseguire il video:
