Oh, and in case it wasn't clear, it's best to have only one run of 
mythfilldatabase per day, and to use --dd-grab-all, whether you run it 
using the suggested next-run time or using a specific time period.  
Ideally you'd use the suggested next-run time (and if you do, you'll 
probably get results as good as using a run at 5pm--or even better 
results because you may get your update in time to fix the afternoon 
listings, too).

The problem isn't the download size (and, really, one day isn't /that/ 
much smaller than 14 due to the number of reruns, etc. within the data), 
but with the server resources (CPU time and memory and ...) to create 
your "personalized" data (for your specific lineup and selected 
channels) for the download.  So, in fact, doing 2 "single-day" runs (the 
default configuration for mythfilldatabase, when it downloads tomorrow 
and +13 as 2 separate downloads) is /much/ worse than doing a single 
14-day run (using --dd-grab-all to just download all the data 
available).  That's why this is one of the few cases where something 
that's better for you (using --dd-grab-all to get all available data and 
update every day's listings to the most-current data possible) is 
actually better for TMS (because of significantly reduced server load).
