In addition to Nick R's very useful info, I think the following still
applies to how the listings are used to populate this information:

If using EIT data, the video details (HDTV, WS) are extracted from the
EIT data (usually the end of the description field) using one or more
regexes before the data hits the database. If the regex is not
matching different variations in how the data is provided, or if the
data is not present for all channels, MythTV will not be able to
provide it in the manner.

If using XMLTV, the data is present in the XML listings if either
specifically made available from the RT, or if the grabber itself
populates the data "somewhat intelligently" based on channel metadata
used by the grabber.
