Hi, I am just looking into buying a recordable DVD. I in particular have been looking at the panasonic dmre55ebs. I notice you can only record onto DVD RAM discs. Which is better, one that records onto DVD RAM discs or DVD RE-Writeable discs? Someone said today that they thought DVD RAM discs are the beetamax of the future?? and can I confirm you can re record over both?? Sorry to sound a bit dense but I am not so good with technology!
