Is ImgBurn planning on an update? It's been years since it was updated as far as I know. We were talking about it somewhere here...If Digistor is still using Panasonic blanks they're among the best media you can get ...better than Verbatim
...and please don't repeat that Panasonic media is B grade if you don't want to embarrass yourself.
@montevideano
Would you please check the blanks' Media ID in ImgBurn ?
If you don't have the Professional Grade ones it's probably CMCMAG DI6 - and those just don't work well in LG and LiteOn burners.
