I have put several VHS tapes (home stuff) onto the hard-drive and then I burn it to a Memorex DVD-R. The problem is I cannot get the disc to play on any of my other DVD players other than the Panasonic DMR-HS2. I also have a Sony DVD and a brand new JVC XV-S500 region free player... and they all say "No disc inserted". The VHS are watchable on the hard-drive. Is there something I am doing wrong? Is there a finalize disc button or setup? Help.
