Are there any suggestions on CD's for yoga? Either helpful newer ones or old favorites?

I will be moving and will not have a Y available. I have not done yoga before. I find I am getting stiff and do not take the time to stretch. I do tai chi but also have trouble finding the time. The reason I stayed away from yoga is it seemed too slow and not to benefit me, only add to pain by stretching too far or wrong. By not benefit me I mean I have too much energy and yoga did not seem to expell it. Now I find I need stretching so it may be helpful.

Thanks
