Just installed RockBox (www.rockbox.org) to my 30GB iPod Video. So far, I like it as it gives MUCH more information than the generic firmware provides. I’ll have to see how stable it is, though.
One gripe right from the start was the RBUtilQt program that is available couldn’t detect my iPod. However, when I ran the ipodpatcher.exe program, it found it just fine. The RBUtil program states that it has problems autodetecting some devices, but I couldn’t get the manual configuration to work either. After installing the bootloader via the ipodpatcher.exe program, though, RBUtilQt was able to install the actual RockBox program, along with themes, fonts, etc.
Looks good so far!
