Pilates DVD? Horse rider exercises?

I used to do pilates classes, I loved them and my flexibility improved dramatically. Then I moved and used a DVD instead because getting to a gym was not so easy. The DVD was 'The New Method Precision Pilates, sculpting an toning'. I did it a few times but for some reason although the exercises were pretty similar, somehow it just didn't click with me - maybe I just didn't like the instructor, Jennifer Kries' approach. That was years ago and now that I am relearning to horse ride, I think that pilates would help with my flexibility and core control which I now realise are shockingly bad. Can anyone recommend an alternative DVD or online video workout? Or are there any other off horse exercises that would help (particularly hip flexibility and core control)?
