Prenatal Yoga Video Recommendations?

I'd been taking yoga classes for a few months before I got pregnant, and now that I'm out of the sick/exhausted phase of the 1st tri, I'd like to pick it back up. Unfortunately there are no prenatal classes offered in my area, and I'm not sure I trust myself enough to modify a regular class properly on the fly. Anyone have any good video  prenatal yoga recommendations so I could do it at home? I would say I'm between beginner and intermediate, and I'm looking for a moderate workout with meditative elements, but nothing over the top 'earth-mothery hippy-dippy'. Thanks!
