CloneCD stop working

Today cloneCD stop working with my blank DVD-R disc. It gave me a writing error. The discs work fine with other programs and worked fine with cloneCD until today. I use unbranded discs. Anyone know a program that copy movies that dont need compression. I know that CloneDVd and 1click copydvd do it but they are slower than CloneCD

I just made an image of a DVD movie to harddisk. Then i used a DVD-R disk to burn to.
I did not use max but changed to 4 x speed.
It burned as useal to 100 % and all went all right.
Used cloneCD downloaded from homesite of Slysoft and updated my 5261 version.
No problems at all.
No overburn request or anything else.
