The bandwidth isn't the constraining factor for TMS.  It's server 
(computational) resources.  When every single DataDirect user has a 
unique lineup, creating daily hashes requires /more/ resources than just 
downloading again.  However, there's no nead to download again because 
Myth does it right.

If you can see the show on http://zap2it.com/ , you can rest assured 
that it will be in your updated listings for "tomorrow".
