Teac & 90 min cdr's




I have Teac burner model CD-R56S With 1.0Q firmware.
when I put a blank 90 minutes cd’r, the burner
cannot read the cd’r and cannot burn.
I “play” with jumpers and convers it to Teac CD-R55S.
Now the burner finally “accept”(read) the cd’r ,but show
me that the cd’r has only 80 minutes (700 MB).(Nero cd speed)

What to do?
I know that my burner suppert burning above than 80+ minutes.
89:xx min

I tried with DiscJuggler, nero , cdr win

Need help !!!
