90 min cdrs

[ickle_moi]

I have recently gotten hold of some 90 min cdrs
and after seeing the cdr articles on gamecopyworld assumedthat my Rewriter (MITSUMI 4804te) would burn 90 mins as it was one of the 2 writers that passed the 99min tests (99:05mins up yours plextor lol)
But all the software i have tried to burn 90 mins with wont let me burn saying there is not enough room on the cd (thinks its 80 min)
ive tried latest Nero, winoncd 3.8, and cdr win all with no luck as it just wont even try burning it
ive also upgraded to latest FW (v.5) with no joy
can anyone help??
