I’ve just tried to burn a DVD into SVCD with Dup-dvd. Everything went well until the first disc(VCD) was burned. The information said that it would take 4 discs to copy it all. And when the first was done and automatically ejected, I placed a blnak one in, and waited. Nothing happened. So I pushed the “copy” button, and the whole process went all over again. I copied the same thing twice. Where did I do wrong? Please help. Thanks.
