just got my first DVD recorder it's a akai adr-5800di model, so it's a dual recorder it records in both R- & R+ so i bought some DVD-RW discs from dixons took them home, then started to play with me new toy only to find it was'nt recording proply, it was playing a bit then freezing then jumping forward to the next chapter and sometimes missing the first 5 min's of a recording, so i took it back and got a brand new recoder but that did the same, i now think it's the discs. does this recoder like to use DVD+ discs better than DVD- discs? or is it cos i've bought cheep ones from dixons?
