Hello Wallaroo – I apologize for the delayed response to this!
At the moment we have no plans to introduce video demos of poses – instead we spent some considerable time and effort putting together “Pose Tutorials” for many of the poses. These used to be accessible as part of a now discontinued Private Members Club, but we found more people wanted them on DVD … so here they are:

There is one on Dandayamana Janushirasana of course (probably our most popular Pose Tutorial actually!), and the idea is to break down the pose into all the component forms and to examine how to correct the common mistakes in even more detail!

In respect to video generally though, it is possible that we’ll introduce more videos in the future, it’s just that there are no concrete plans for now – it can be expensive and time-consuming to get the production quality that we would want.
And finally – if you are willing to describe your challenges here on this forum, we’ll do our best to point you in the right direction 😉
