Incomplete file transfer from TiVo to PC

I record a show on an XL unit and subsequently use TiVo desktop software to transfer the file to my PC. Most of the time this works well. However, from time to time the entire file does not transfer, e.g. an 11 GB file stops transferring after 5 GB has transferred. The show plays fine on the TiVO, but will not allow a complete transfer. Has anyone experienced this issue and is there a work around?



Additional notes. The transfer is via wired Ethernet. The same results happens using a browser transfer.
