File field meta data

If I use filefield to upload files and filefield_meta module is enabled too, when I upload a file a record with some informations is written in {filefield_meta} table
When we convert a video or delete a video/node this information are not updated.
I don't know if is a good thing to add this feature in this module but line 60->63 works for me

function _flashvideo_perform_postop($oldfile, $newfile, $node_type, $create_thumbnail = FALSE) { 
2 
3   $timestamp = time();

8     // Insert this video into the flashvideo table if it is not already in there. 
9     if (!db_result(db_query("SELECT COUNT(*) FROM {flashvideo} WHERE oid=%d AND fid=%d AND nid=%d", $newfile->fid, $newfile->fid, $newfile->nid))) { 
10       // Insert this video into the flashvideo table. 
11       db_query("INSERT INTO {flashvideo} (fid, nid, oid, status, video_index, width, height, flags) VALUES (%d, %d, %d, %d, %d, %d, %d, 0)", $newfile->fid, $newfile->nid, $oldfile->fid, FLASHVIDEO_STATUS_CONVERTED, $params->video_index, $params->width, $params->height);
