I'm having a similar problem to one I noticed in a different post, here: http://xdaforums.com/showthread.php?t=1987102 . I need to save HD video to an external storage device directly, as this guy wanted to do. However, every camera app I've tried, and ursafe media director doesn't recognize my usb otg hard drive as a location. the only way I can browse it is through file manager. Any suggestions? I have a Lenovo S-3000, takes 1080p video, and I want to be able to record directly to a thumb drive with it. Thanks in advance!
