I keep vowing to stop watching the live shows because they are never worth the time investment, but alas I am weak.
A good trick with the main show is to DVR it and then start watching it about a half hour into airing while it is still recording. Then by fast forwarding through commercials and promos for other TLC shows you finish right around the same time you would have if you watched it live with commercials. This is great for baseball games too. Don’t start watching the recording until an hour into the game.
