I've been doing yoga fairly regularly for about 3 years now. Among its many benefits, for me the main benefit is increased flexibility. I'm naturally pretty flexible but yoga has taken my flexibility to a whole new level. Other benefits I've seen have been improved core strength (which includes back) and increased upper body strength, particularly the triceps. I used to have lower back pain from time to time and that has completely disappeared. The feeling I have after a session is indescribably relaxing. I feel like a serene ball of goo.
The way I am currently including yoga in my rotations is by doing "full" (i.e., 60 min) power yoga sessions twice a "week." (My "week" is 9 days.) In addition, I sub a 15-20 min yoga stretch for Cathe stretches so that I'm doing some kind of yoga almost every day (which I've read is important to continue making progress).
I won't recommend any power yoga DVD's because you wanted something shorter and less athletic. I'll just list DVD's I use as add-ons to my Cathe strength/cardio workouts:
- YOGA FOR ENERGY (Rodney Yee) - 5 segments, none over 20 min
- YOGA CONDITIONING FOR ATHLETES (R. Yee) - 3 20 min segments, plus several other 5-10 minute segments geared toward specific sports
- SONIC YOGA TURBO FLOW (Jonathan Fields) - I don't care for this practice (it's lightening fast!) but the last segment, "Dissolve," makes a wonderful 10 min add-on. I use this the most.
- YOGA ZONE CONDITIONING AND STRESS RELEASE (Alan Finger) - I only do the neck/shoulder stretch segment and it never fails to loosen me up when I'm tense or have pain in that area.

Good luck! If yoga doesn't click with you right away, try to hang with it for a few weeks. Many people find it awkward at first but then fall in love with it, especially after they get better at breathing.
