Yoga for pregnancy recs?

[kaethe]

I'm about 22 weeks pregnant and have recently had a flair-up of plantar fasciitis (hope I spelled that right). Walking for exercise isn't happening right now, so I'm hoping to use yoga to help build my core strength and otherwise prepare for labor.

Does anyone have any suggestions for yoga videos (online or DVD, either way) that are good for pregnancy/labor preparation? I've looked at Amazon, but there are so many it's hard to know which ones are worth the money.

As for my experience level, I'd say long-term beginner. I've done yoga off and on for about two years, but stuck to beginner-level DVDs.

Thanks in advance for your help!

Increasing frequency and intensity

This relates a bit to the question below from alexseanchai.

My local studio is offering a special course soon, where you do a fairly intensive run of yoga for a month. It's not an "advanced" course, it's open to every ability, but it involves about five classes a week plus some seminars and such. There's a variety of classes and some are definitely more challenging than what I'm used to.

When I first saw it, I thought it was something I'd love to do in future, but not now. I currently do one class a week and that's it (I rarely practice at home), so jumping to five classes a week, including more intensive classes, didn't seem like the right thing for me.

But now I'm reconsidering. I think the course might be a good opportunity to kick start me to better and more consistent practice, which is something that I want and haven't been able to do on my own yet. I usually respond well to the structure of a course, and I always get a lot further when I do a course than I do by self direction. The studio does a great job of mixing their classes for all ability levels, so I do trust that I could get something from the more challenging classes and not feel pressured to overdo it. But I'm definitely not sure if making such a big jump in practice in a short time will be a good idea.

My question is, does anybody have experience with doing a sudden increase in frequency and intensity of yoga? What happened for you?
