Base hours, yes. My longest sessions are in the 5-6 hour range, and this year I've done some 3 hours and one 4 hour. Right now a regular ride is 1.5-2 hours.

During the season I'll do some hours too, maybe an hour on a given night.

I ride outside too, but the trainer is a familiar place.

I rarely watch movies except on very long rides. Movies tend to be least motivating for me. I usually watch race DVDs (I have maybe 30? they aren't that costly if you get a bunch at a time from WCP, and the long Grand Tour ones are great); I'll watch my own helmet cam clips; and when I want to work hard, I usually focus more on music. There's a very narrow selection of music I listen to on the trainer, mainly stuff from my clips. When I ride hard I don't open my eyes much, and when I do I'm looking down. The TV gets ignored.
