I'll help pitch in for a few of the codecs. I'll start with SPC and NSF, but I also want to know if other Rockboxers can give me their experience with these two codecs. I've noticed that they both run great on Coldfire targets (iriver H1x0/H3x0/X5 & M5), but on my iPod video (and I'll bet on other PortalPlayer targets), they tend to stutter quite a lot. So, can anyone else help me verify the performance of SPCs on their platforms?
