I just wanted to say that I appreciate the Rockbox coders. I had tried Rockbox about a year ago and even converted some of my music to ogg format but it did not play very well. I wiped out Linux on my Mac and reloaded it with OS X and I also wiped out Rockbox as it did not do any thing for me that the Apple Firmware did not do. In the mean time I have all my music in AAC format. I always had to use the build from Mikeage as I could not get Rockbox to play more then a few songs before locking up. I was getting the same error that others were getting undefined instruction after playing a good amount of songs but then when I rebooted it would come back again after playing just a few songs. I appreciate the work that went into fixing this and glad that I gave Rockbox a try again. A lot has changed and I am sure that more changes will come.
