If you have some script set up to automate much of this process, I would 
actually consider it better to have that script add the video itself.  
Tacking this onto the end of the script should perform the same process 
as the scanner would, only selectively.

from MythTV import Video, VideoGrabber
vid = Video.fromFilename(<filename relative to SG root>)
## if movie
grab = VideoGrabber('movie')
res = grab.sortedSearch(vid.title)
if (len(res) == 1) or ((len(res) > 1) and (res[0].levenshtein == 0)):
## if television
grab = VideoGrabber('television')
res = grab.sortedSearch(vid.title, vid.subtitle)
if (len(res) == 1) or ((len(res) > 1) and (res[0].levenshtein == 0)):
     vid.importMetadata(grab.grabInetref(res[0].inetref, res[0].season,
