I am thinking of getting a DVD writer but dont know a lot about them. I have tried reading as much as I can on the web, but am still confused. I want a writer to back up my PS2 games, dvd films and general back up of my system. I have seen the NEC ND1000A DVD+R Writer going for £120 and the PIONEER 105 DVD-RW X 4 Speed Writer ( OEM ) going for £210. Apart from the price what is the biggest difference between the - and + formats? Which would suit my needs better? Thanks for any help you can give a DVD noobie.
