hey! I have the same problem, except I did use the patcher. I extracted following files onto my Ipod 5th (Video, 80Gig) Generation:
-> rockbox
-> rockbox-ipodvideo64mb
-> rockbox-fonts
then I put the ipod into disc mode by restarting (Menu & Center/select). as soon as it reseted I puched "play" & "center/select).
So far everything was fine the ipod in disc mode and connected to my notebook which runs WinXP home edition, by the way.
I then downloaded the iPodpatcher, as I was told by the manual. I ran it from my desktop. but it couldn't find any iPod device. this is what it says after the introduction above:
[info] Scanning disc devices...
[ERR] no ipods found, aborting...
[ERR] please connect your ipod and ensure it is in disc mode
[ERR] please refer to the rockbox manual if you continue to have problems
please press ENTER to exit ipodpatcher :
any suggestions???
thanks
Chris
