I am a new imac user and have been using the 'burn' (that's the actual name) program for months without fault. All of a sudden i was unable to burn DVDs. the process would work as normal until the very end when the disc was ejected and the program would say burn failed because of the disc drive (or something like that). I've tried re-installing the program but the same thing happens except now it just says unable to burn and cannot retry. I've tried Resetting PRAM and NVRAM and doing the hardware test (which found nothing wrong) and nothing has worked. I really would like to keep using 'burn' because its so quick and easy but if there is anything out there similar or better (but still free) let me know! Any help would be GREATLY APPRECIATED -it actually says "The device failed to respond properly, unable to recover or retry."
