Dvd shrink / nero 6 problems

Dvd shrink / nero 6 problems

I must have used these 2 programs for 6 months without problems, however yesterday when the change-over from shrinking to burning starts I get an error a few seconds into the burn and it informs me “burn failed”
I have checked both progs and both work fine , but the above setup when 1 automatically starts after the other has finished shrinking is causing probs

Any ideas??
