vegetaleb wroteIt's weird!
It worked on a IBM laptop but not on Lenovo desktop,nor mine (custom made),nor Toshiba laptop.
We did a format and burned a movie on the IBM,it played fine on all the other PCs but if I try to format it on my PC it will hang and fail.
Tried with an old Imation DVD+RW this time and worked flawlessly on my PC in format and writting.
I think my new Pioneer BD writer doesn't like imation DVD-RW but DVD+RW
Wll try with another brand
Lenovo and IBM are the same brand.
But considering the IBM is old, it will have slower Read/Write speeds. The faster you burn disks, the more errors it will make. Burn at 1x and see how it works. If disks were left in the sun (or let's say the car) the heat will ruin it.
