Just thought I'd thank the Rockbox team for their efforts, and for the forum
I've just installed Rockbox on my ipod video yesterday and had alot of fun fiddling and setting it up the way I liked yesterday, but this morning my ipod appeared dead, for some reason :S
Still, I found the forum here and, before posting, scanned through a few posts and I found several posts telling me to hold the menu+select button for longer than several seconds. It works!! Thanks again and just a message to others, to reset hold for at least a minute until you give up.
