Using the same machine - NO - it only has the one DVD tray as do all the other machines, but there is a way it can be done.
The Panasonic DVD PLAYERS also play DVD-RAM discs recorded in both SP and LP mode. I sometimes transfer this way using the player connected to the DVD recorder. I use the Panasonic S27 player but JVC and NAD dvd players will also play dvd-ram discs as will a few PC writers with the LG and Panasonic PC writers also recording to ram discs.
A contributor on one of the recent threads on this forum has pointed out that it was necessary to set the DVD-RAM disc to "locked" on the Panasonic recorder before he could play it in his Pioneer A106 writer.
