The WD uses TVDB.com for its automated media scrape and since they only list individual episode and not DVD discs that’s why it’s not returning any info.
You can either convert individual episodes using Handbrake to get automatic info for each episode.
Or you can do what I did and use an XML editor like the WDTV Live Hub XML-Editor to create your own XML’s for each disc:
and don’t let the name fool you it will work with the WDTV Live SMP.
Both are a bit time consuming but from what i’ve found these are the only two options
