[Plugin: Add From Server] not adding full MP3 files/ Podcasts

I am in the process of putting up podcasts. My MP3s are between 50 and 70 MB each, all around 30 minutes in length. To upload the files to the WordPress Media Library, to use with the PodPress plugin, I’ve been uploading via FTP and trying to import to the Media Library using the “Add from Server” plugin. The “Add from Server” plugin only adds the first 11 minutes or so of each file. I’ve triple-checked the files on the server and they match the originals in size and length.

Is there another way to import large files to the Media Library? Has anyone else had this problem with the “Add From Server” plugin? If so, how did you resolve it?

Thanks!
