Hallo,
on the german Hanggliding organisation (www.dhv.de) you find also some educational videos for certain problems (e.g. asymmetric deflation) during Paragliding.. unfortunately only in german... but when desired I can translate the text help you with the translation when necessary... or you try it with a translation program

Furthermore I have 2 CDs schools use for teaching showing videos how to start, land, and to fly available. Unfortuantely the Text is also in german, but just the images might be helpful...I can help you with the translation when necessary...
If anyone is interested, please notify me via email and we can send you the links or to find a way to get the CDs....

regards Guido

P.S there is also a mailinglist which notifies you (also in english) about certain problems with hanggliding or paragliding equipment... found at:
