Received my Zen Portable Media Center several weeks ago. Downloaded the new Tivo Desktop 2.1. But when I try to sync .tivo files with PMC I get the following error: "Server threw an exception". Microsoft support says it is a codec problem. http://support.microsoft.com/?kbid=884841 Purchased the CyberLink PowerDVD 5.0 SE codec. (previously the free codecs had worked on syncing to my palm via kinoma producer) But I still get the same error. I even tried a regular MPEG2 video instead of a .tivo file. Same error. Anybody have similar problems?
