YAMJ is not correctly mapping the "container" tag of an NFO file to the "container" tag in the resulting XML file. Instead, it appears YAMJ will take the value of the "videoCodec" tag from the XML file (it appears the NFO "videoCodec" tag is not mapping over as expected to the "videoCodec" tag in the XML file as well, with any NFO "videoCodec" tags being imported as a second entry in the XML "codecs->video" tag).
