Colombo:
And more information:
mp3 cant play at 24 and 30!! It automatically change to 75Mhz and reduce playback time to 5 hours,
But FLAC work normal at 30Mhz.

BTW, original firmware play mp3 at 24Mhz -> 14 hours. Too bad for rockbox :(

Llorean:
How do you know what frequency the original firmware plays it at?

Hi, i'm not sure if this is true.
As far as i know the bad runtime is because there is some conponent in the player that draws more power than it should. And because the portalplayer chipset used in ipods is not very well documented it is hard to find the cause for the low runtime.

saratoga:
Theres no way the OF runs at 24MHz while decoding.

Only at 24Mhz ipod nano can work 14 hours. 75Mhz - 5 hours.
