I'm starting to think I-Pod! Just got an H10 20GB back via exchange because of "missing files" message. Got this one back and hangs WMP10 endlessly ... worked once with Rhapsody, but now hangs that too ... Tried reloading firmware, uninstall and reinstall WMP10 ... NOTHING WORKS! Any suggestions before I try returning again? I have an AMD 3200 machine with 1.5G of memory and my IRiver seems to be dead in the water.
