i have understand that to make the original ismv file is necessary download all the fragments with the download manager because only in this case we are sure that all the segment downloaded have the same bitrate(clearly to have the best quality is necessary download all the fragment with the highest bitrate)...then the operation is not possible during the view mode because difficultly the fragment downloaded have all the same bitrate or the same and the highest bitrate...now i would make a patch that creates the original ismv file or an mp4 file (that however is the base of ismv file)but i must study all the tags obligatory for the creation of mp4 or ismv file...moreover is important extract mdat information from the chunk downloaded
