I plonked an SD card into a USB SD card reader and connected it to the Co-Star. The unit recognizes the USB device and confirms 'syncing', but how do I view/play the images? I've the the full manual end-to-end, tried a bunch of ideas, but to no avail. There also doesn't appear to be a way to add a USB device to 'Devices' so there has to be some sort of direct viewing method that I've not been able to fathom yet. One last thing, I've tried the 'input' button on the remote, but all that brings up is recently used/seen items. Can anyone help please?! Thanks.
