I had a dvd I tried to list on swapadvd but could not because it only has a isbn number for some reason. It is a dvd set has the dvd , yoga cards and a band, its a yoga dvd. Where would be the appropriate place to list this?

The DVD site is the only place DVDs can be listed. If its not recognized by the system, you'd need to offer it in the Bazaar there. DVDs are not swappable on PBS.  You would only get the one credit per DVD, the extra non-media stuff doesn't earn any more credits and you wouldn't be able to use media mail to send it so swapping it might cost you more than the credit is worth.

actually you do not post DVD's with the ISBN you use the UPC code.

Since it does not have a UPC, then post it in the DVD Bazaar on SwapaDVD.  Those type of DVDs usually get picked up pretty fast.  I'm a frequent visitor of the Bazaar there :)
