(sony rdr-hdc100 swithes off after a few seconds.) My answer was to press stop on the remote control while "loading" . Seems it is trying to play from the hard drive, pressing stop halted that. I had tried many other things from the Internet, but none worked. What made me try that was that I noticed hdd was shown on the front, so I assumed it was trying to play from there.
