I use the custom iPod software RockBox ([login to view URL]) but it does not support the audio formats MOD, IT, or XM. Wikipedia has some information on them but I'm hoping the coder can do their own research and possibly prior experience to update the current build for at least the iPod Video 30GB rockbox source code. Rockbox is open source and I expect the coder to commit their final code. I will update my iPod with the software and test various files to ensure functionality. I look forward to working with the winning bidder in the future if they do a good job.
