Oh, Sabine, I'm in the same boat. My Body Blast DVDs have been here for ages, and I can't play them! It's so frustrating! I was planning to just pop them into the computer, like I do with movies sometimes, but they don't work! I've tried downloading players, decoders, etc., but I ended up spending $30, then 6 hours fixing the computer because one of the programs messed everything up. I've decided to wait (and hope) for a DVD player. Hope yours arrives on schedule, too.
