Comment(by gnome42):

 Ok, I think there is a race concerning the setting of the keyframedist
 when livetv is started.

 The race is between the backend recorder inserting the initial position
 map into the DB and the frontend retrieving that position map and setting
 keyframedist via SyncPositionMap(). When the frontend fails to get the
 position map the first time it attempts to fall back to ffmpeg seeking
 which is not supported for livetv.

 The attached patch addresses this by adding a few checks for livetv and a
 check to ensure keyframedist is set correctly before it is used.
