Also i not see in the code any reference regarding mp4 or vlf anly about .mp4v, I ask this because out of several hundreds of videos, the transfer script only transfers 3

                $sFileName = "{$aValue['ID']}.m4v";
                $sVideoPath = $this -> _sVideoFilesPath . $sFileName;
                if (file_exists($sVideoPath))
                {
                    $oStorage = BxDolStorage::getObjectInstance('bx_videos_videos');
                    $iId = $oStorage -> storeFileFromPath($sVideoPath, false, $iProfileId, $iVideoId);
                    if ($iId)
                    { 
                        $this -> _iTransferred++;
                        $this->transferTags((int)$aValue['ID'], $iId, $this -> _oConfig -> _aMigrationModules[$this -> _sModuleName]['type'], $this -> _oConfig -> _aMigrationModules[$this -> _sModuleName]['keywords']);
                        $this->transferFavorites((int)$aValue['ID'], $iId);
                        $this->transferSVotes((int)$aValue['ID'], $iId);


                        $this->_oDb->query("UPDATE `bx_videos_entries` SET `comments` = :comments, `video`=:video WHERE `id` = :id", array('id' => $iVideoId, 'video' => $iId, 'comments' => $this->transferComments($iVideoId, $aValue['ID'], 'videos')));
                    }
                }
