For those of you out there training and using ActiveTrainer, I have created some swim training plans with iPod/iPhone videos, which you can take to the pool with you, to help demo drills and skills.
The plans are written as two days of workouts and new drill introduction, (Mondays and Wednesdays), and then another fitness-based workout which combines the skills of the week into a single workout. Every other week has a fourth workout, which is optional or can be switched around during the week.
If you're a triathlete looking for swim help only, and want to do your own bike and run training, then these plans are for you. You can simply add these swim workouts to your training, and adjust as you see fit.
Check it out here under Triathlon or Swimming:
There are three plans, Level 1, Level 2, and a combined one for cheaper of Levels 1 and 2.
If you use these, I'm sure you'll learn a lot, and improve your swimming!
Best of luck!
