the encryption used on the crypto transform-set and the isakmp policy don't match each other on both pix's.  

basically phase 1, they negotiate to use 3des/sha, but when they get to phase 2 try using des/md5 and fail.

The policies are fine.

Enable debugging (deb crypto isakmp and deb crypto ipsec), try to bring up the tunnel and post the result.

This shouldn't be closed.  There were two experts helping and I gave a suggestion to solve the problem.  At the least, it should be stated what the solution was.
