It's slow since it needs to iterate through all recordings and check file size of the index file (thats what i understand from Klaus comment), so divide that by number of frames of the recording and thats it. the directory scanner is anyway doing the same (iterating the video directory and pick up necessary information). So it wouldn't add anything substantially. _______________________________________________ vdr mailing list vdr@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
