I dun know how to use my Ipod *cries*

I did managed to sync 12 South Park episodes on to Ipod la. And 14 songs.

I read somewhere once you register your Ipod to a PC, you cannot use other PC anymore. How??? I registered using my office PC orh. There are lotsa songs in my home's PC that I still want to sync. And that if I want to sync, I have to re-register using my home PC and all the songs and videos previously stored in Ipod will be wiped off. Wut da fark???

*wails................................................*

Org bodoh..got canggih player in your hands but dunno how to use...
