A quick Google gave the following thread:http://stargazerslounge.com/imaging-image-processing-help-techniques/73377-stacking-dslr-registax.htmlwhich may help.I’ve never hit this problem, but I’m only using a webcam so small files.How big is the file, what size image, what camera, does windows media player run it OK… etc? may help someone else solve your problem.
