Well, I do know that the old forum only would accept wmv files. So, that could be the same reason here. But hopefully, admin will help shed light on this.
Hey guys, it appears this is only possible with the Media Gallery software option. I will purchase this soon and let you know when it's up and running.
At present, images are limited to .jpg (larger in physical size, smaller in file size) and .png (smaller in physical size, larger in file size). Video files are limited to .wmv
