[mythtv-users] Manual Scheduling Subtitles

[D]

Zap2IT has innacurate listings for Comcast local tonight, so I have to
manually record a bball game.  Myth is forcing a subtitle involving
the date/time, ignoring what I set it to when scheduling it via
mythweb.  Now I understand the concept, to avoid dupes...but will it
be safe to change the subtitle by editing the DB directly after it is
all said and done? Or can you edit it from within myth?
