My DVD recorder takes DVD +RW and -RW. I have always used -RW to record and edit, and can use the same disc for many recordings at many times, building up a full disc over time. I am unable to buy -RWs from anywhere now, so have started using +RWs. But if I set the recorder to record a 30 minute programme with the total time on the disc set to 4 hours (so I can record another 3 1/2 hours programmes at other times), on ejection the recorder finalises the disc so I can record nothing else on it. The problem is not with the recorder as -RWs are fine. So is this the nature of +RW or have I bought a pack of duffer +RWs (Maxell)?
