1) Run WebEPG-conf.exe
2) Click the Import button to import all channels from MediaPortal
3) Map one channel (as I can only fine one Channel that WebEPG is configured to download). This leaves all the other channels blank, with no mapping.
4) Click Save, and close WebEPG-conf.exe
5) Run WebEPG.exe
6) Review the contents of Log\webEPG.txt and XMLTV\TVguide-writing.xml and note the error: "[ERROR][1]: WebEPG: Value cannot be null. Parameter name: key".
7) Notice that TVguide-writing.xml does not get written to TVguide.xml

This fails:

This works:

<?xml version="1.0" encoding="utf-8"?>
<WebEPG xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

  <ChannelMap>
    <Channel id="Eastern@fox.com" displayName="36" grabber="US\tv_yahoo_com.xml" />
  </ChannelMap>
  <Authentication />
</WebEPG>

IMO the best solution is to have WebEPG.exe skip the blank mappings. A second (though much worse option) would be to have WebEPG-conf.exe automatically delete blank entries on save.
