I have come across a great Autism spectrum disorder Video Glossary

You have to register first but it's simple although it requires your email and name.

This glossary contains over a hundred video clips and is available to you free of charge. Whether you are a parent, family member, friend, physician, clinician, childcare provider, or educator, it can help you see the subtle differences between typical and delayed development in young children and spot the early red flags for ASD. All of the children featured in the ASD Video Glossary as having red flags for ASD are, in fact, diagnosed with ASD.

Norton flags the site as Safe so dont worry about spyware etc.
