I think there are two ways:
1) Convert all the codes to Pronto Hex (we can help with that), identify the functions that aren't already in the Harmony, and send the Pronto Hex for the new functions to Logitech, with a request that they add them to the setup for the XV-DV313.
2) Get a UEI manufactured remote, use setup code Audio 1384, and enter a 5 digit EFC to assign each new function to a button. Then teach the functions to the Harmony. Suitable remotes include any Comcast, Atlas remotes used by many other cable companies, many OneForAlls, high end Vizio remotes, some Radio Shack, and some RCA. The EFCs are listed below.
The DV313 uses a the Pioneer two command IR protocol, in which many functions require sending two commands. In the below table, those functions are listed as having a prefix device and prefix command. See if any of these are likely to help. Sorry about the formatting -- the EFC is 5 digits, and there's no space between it and the prefix device.
