In the face of data loss on connections between a content source and a content consumer, additional connections therebetween are opened. These additional connections are preferably opened between the content source and a proxy disposed between the content source and the content consumer. The proxy may then seam together data streams received from the content source across the additional connections in a recording on a computer-readable medium. The seamed stream may be constructed by filling in information gaps in any of the data streams received from the content source with content derived from others of the data streams received from the content source. This derivation may be made on the basis of identifying characteristics (e.g., packet contents) of packets from each of the data streams received from the content source.
