If you have a an iPod Touch or something else you can put videos on to go, here's something that might be worth doing. Using iTunes, you can subscribe to the Church's General Conference broadcasts for free. It takes a day or two for them to show up, but you can get all of the talks downloaded onto your computer or portable video device.
If I'm waiting for a doctor's appt. or something like this, I will watch them on my iPod. If you're into listening to the audio, you can get the free audio downloads as well via iTunes.
