Since all of the stores now only carry 16x speed media, my 4x speed drive that came in my G5 PPC won't work any more with this media (for some reason it did fine with the 8x speed stuff). I've heard it needs a firmware upgrade but I've searched the planet hi & lo and the only ones online are for PCs and nobody else understands what I'm talking about or wants to deal with it. So I'm over the firmware thing and just want to replace it with a new 16x speed/ dual layer internal. I've heard they are available online for about $30. Can anyone recomend one that will plug right into the cable in my G5 PPC and for sure be compatible with DVD Studio Pro ?
