I read many post about "power calibration error". I have the same problem but with princo media, only when i try to copy DVD media and only the first time (i use pioneer 107D).
i test it with dvd identifier:
Unique Disc Identifier : [DVD-R:PRINCO]
Disc & Book Type : [DVD-R] - [DVD-R]
Manufacturer Name : [Princo Corp.]
Manufacturer ID : [PRINCO]
Blank Disc Capacity : [2,298,496 Sectors = 4.71 GB (4.38 GiB)]
DVD princo isn't of good quality?
Thanks for reply
