Hi Hollie,
Spinning does involve out-of-the-saddle work but I don't think that should deter you. There are plenty of recumbent cyclists on the road & they manage just fine. You just won't have as many options.
An indoor video involves climbs (lower cadence & higher tension) & flats (faster cadence & less tension). Using a video is much more stimulating than Headline News or some trash tv (though a favorite CD isn't bad).
I'll let someone else post their favorite videos. All things equal, a workout with less time out of the saddle (on the video) would be better for your situation.
