I'd would like to port rockbox to this "mp4" just because this is the
only one i have, and it is quite limited. The sound quality is very
good, but it's video format is very very lame... NXV video format is a
collection of RAW images with mp3-encoded sound...
A RMVB (20min/40mb) can easily turn into a 700mb monster...

i would like to backup the current firmware in case that i want to
back to the normal firmware "mp4"... After all, this is the only that
i have... =(
