Video ModX support?

Hia, I am pretty new at using ModX. I have used other CMS before but thought I would give this a whirl as it uses AJAX, something that I think if a step forward!. Does anyone know if there are any good video tutorials of how to get to grips with ModX and how to use snippets and chunks and TV’s and how to customise?

Does anyone know of any other videos that would help me get to grips with how to use snippets for Modx MaxiGallery which looks fantastic but I cant seem to be able to upload and I am not sure if I am using the correct path!

I know Mark has created webcast for Ditto but I am unaware of other video tutorials regarding MODx... This is one of the things we’d like to have but it’s not easy to make the time to build those...
