When using CloneDVD2 in a VM using two drives, one to read an one to write and will not write to the second. CloneDVD reports both as DVD writers, thogh the VM seems to considder the second one as astraight CD or DVD, no write. Running the same program in a MAC bootcamp works fine. Both DVD's are sata, dual layer, first, Pioneer and 2nd ASUS, though obviously if they work under bootcamp there is nothing wrong with either,
