To be quite frank about it, the only supported CD-R/CD-RW types for the whole iMP series up to the 550 is 700Mb (80mins).
So having probs with 90/99 mins stuff is only to be expected - as this really will only work (after a fashion) for some decks that happen to be super sharp in their tolerences.
And dont forget, burning speed is an issue to account for as much the need for good media when you want the best read performance out the decks.
You could say, along with my anti-shock testing and also abusing iMP's as compressed audio sources for supplying on demand audio in broadcasting, i've kinda been there and done it with the tolerence discover of the older iMP's (250 being the benchmark where ASP was considered to be spot on for performance and early 350's likewise).
FG
