This sounds to me like the usual scan problem: videos are identified by 
hash-value, not by file name. Only recordings with a new hash-value are 
added.  You may need to scan an empty set of directories before scanning 
the ones that you want to use, and don't move recordings that have 
already been scanned into a video directory without 'forgetting' them 
first.  You might find mythlink.pl useful for some of this.
