Training Video for Indoor Trainer

Hello all,

I just recently purchased a CycleOps Fluid 2 trainer.  I've been riding for a little over a year now but my workouts consist mostly of doing the same laps over and over again and a maybe a couple of triathlons in between.  I've always managed to do well on triathlons but at the olympic distances, my lack of training was really apparent when I would just croak on the run having been completely spent from the bike.

When I hopped on my trainer last week, I was surprised how hard the workout was compared to a road workout in the same amount of time.  I want to make sure that I'm doing this correctly though.  I've invested in a cadence computer and would also like to purchase a training video.  Can anyone recommend a good training DVD that goes overall cycling techniques?  Or just an excellent overall video?

Thanks!
