Query: Beware NEC 1100A Owners!!

I had backed up many DVDs on Memorex dvd+r at 4X, so this time i went for the 50pack. The problem is that these new discs will only burn at 2.4X, probably they changed the id coding in the dvds and the last firmware upgrade for the NEC 1100A doesn't support 4X writing on these brand. Now i'm stuck with a 50pack spindle that only burns at a slow 2.4X(about 40 min per DVD). So before you buy i'd suggest you buy a pair of individual DVD's just to make sure they will work on your burner. I'll guess i'll try the HP DVD+R 4X that are priced very similar. And also NEC won't do any more firmware upgrades on the 1100A. The newest version is 10GE and it does not support these. It was released may 2003.
