I have never had a problem recording on the Z7+. The last few times I tried to record, I get the message "can't record this stream". I reformatted a usb to fat32 and still the same message. I did a factory reset. I tried to record on numerous channels getting the same message. It did record an open channel, so I know it is not the usb or the Z7+. I don't know where to go from here.
Thanks for any help,
