The networks themselves don't know what's on 14 days from now... so since anything past Today+1 is "14 days old" at the time of download, it's a safe bet that most of your guide is inaccurate.
If you want accurate data with MythTV, IMHO you should *always* do a ---dd-grab-all, at least until SD self-hosts the data and can offer update based listings.
To elaborate:
By default, mythfilldatabase actually downloads Today, Today+13, and any days between Today+1 and Today+12 that have not already been downloaded. However, some users report that the current day's guide data in MythTV is inaccurate when using the default settings, so it seems that the mythfilldatabase download for Today may not reliably override the previously downloaded data.
Running "mythfilldatabase --dd-grab-all" causes all 14 days of guide data to be downloaded, and all previous guide data in the database to be overwritten, which should eliminate any drift between MythTV and zap2it.com.
To configure MythTV to use --dd-grab-all when running the daily mythfilldatabase job, run `mythtv-setup`, select "General", go to "Program Schedule Downloading Options" (the last page), then set "Guide data arguments" to "--dd-grab-all".
