not a biggie but more for my curiousity. I use both a Mac (w/ iTunes 7) and a PC (with iTunes 6), I wanted the option of uploading songs into my iPod using two different libraries in both my computers. But for some reason, I can't upload songs into my 5G iPod anywmore using my PC library. So what I do is I perform a manual transfer of files either via ethernet/flash drive from the PC to the Mac and uploading it via its iTunes 7 library. Not really a hassle but I'm just wondering why my iPod (although the PC library recognizes it) can't seem to accept new files directly from iTunes 6; when it worked fine before iTunes 7 came out. anyone here knows why? I don't want to upgrade to itunes 7 in my PC because of all the bugs that havent been sorted out in that version. oh, and all my iPods are on Windows format.
