I have never had any problems playing the iTunes Music Store samples until recently. Now I have a problem where the sample quits playing about 2-3 seconds into the sample. Is this a streaming buffer problem? Under edit/preferences/advanced I have tried setting the streaming buffer size at each of the small, medium, and large settings but it doesn't seem to help. I have a very fast cable modem and windowsxp if that helps diagnose anything. I tried searching the forums with different keywords but came up empty. Has anyone heard any solution to this problem? Thanks!
