If it truly is the same version of MythTV on both the frontend and the 
laptop, then it's safe to let the laptop upgrade the MythVideo schema.  
It would also indicate one of 2 things--either your update scripts 
didn't properly restart your frontend process*** (so you're running a 
0.23 frontend against a 0.24 backend, which is a recipe for disaster if 
you continue running it--so well worth exiting the frontend to make 
sure) or your frontend doesn't have MythVideo installed on it (so it 
doesn't know/care about the MythVideo schema).

*** Note, also, that if the frontend is still running the older version, 
it's possible that the backend is still running the older version 
because it, too, was not restarted properly.  A certain distro's 
packaging scripts have been known to not properly restart things after 
an upgrade, so my recommendation is to reboot the whole frontend/backend 
system--to make sure everything restarts properly.
