Thank you jya_ from #mythtv-users (irc.freenode.net) for identifying the location to change the skip time for playback using mythtv.

By default, mythtv skips 30 seconds FORWARD using the Right Arrow Key (->) symbol, and skips 5 seconds BACK using the Left (< - ) symbol on the keyboard. I wanted to change the skip back time to 15 seconds instead of 5...but where did they hide the setting? The adjustment is in mythfrontend. Navigate to the settings from mythfrontend: Setup -> Video -> Playback Groups -> Default

Your screen looks like:

Or whatever works for you. Thanks jya_.

Everytime I looked at the the schedules in mythtv I had gotten from Schedules Direct, They were scrambled. The titles and the times would be correct, but the description did NOT match the programme. I contacted Schedules Direct and found out about something called EIT. Event Information Table. EIT is part of the ATSC standard.

EIT information is transmitted along with the programme from over-the-air broadcasts. The effect is, the EIT information “updates/replaces/clobbers/fubars” the information already present from Schedules Direct, and scrambles the schedule listing.

If you are getting scheduling information from Schedules Direct you need to disable/uncheck the scan in mythtv-setup, Video Sources.

Your screen should look like:

Many thanks to Robert K. from Schedules Direct.
