Some info may be out of date
May I suggest that each MythTV wiki page have a "last updated on day-month-year" somewhere on the page so that the reader may know somewhat whether the info is up to date?
US EIT data
Garbled by a possible bug in the EIT scanner or not, US EIT data is of very little value. Stations are only required by the FCC to provide 12 hours of data, and typically offer no more. The data they do offer is typically without a subtitle, and with a generic description.
