Hi, I have a Toshiba D-VR 16 dvd vhs combi. Just over a year old. It records fine but has stopped formatting blank DVD's. They load, then go to format screen which says 0% and flashes and then comes up with disc record error. I have tried with both Tesco and Sony DVD-RW's but to no avail. About 1 in 200 go's it will format. Any ideas.
