@drinfernoo Yep, I already am using & amp; Kodi just converts them when printing the label control.

Code:

<control type="label">
  <label>& amp;</label>
</control>

Actually outputs a single & and not & amp; 

Sorry for the spaces but this forum does the exact same thing, converts & amp; in to a single &, how did you get them to display in your post?

These are the variables generating the query, again ignore the space in & amp;

Code:

<variable name="Info_Param_Episode_Cast_Query">
    <value condition="!String.IsEmpty(ListItem.Year)">query=$INFO[ListItem.TvShowTitle]& amp;year=$INFO[ListItem.Year]</value>
    <value>query=$INFO[ListItem.TvShowTitle]</value>
</variable>

<variable name="Info_Episode_Cast_Members">
    <value>plugin://plugin.video.themoviedb.helper/?info=episode_cast& amp;type=tv& amp;$VAR[Info_Param_Episode_Cast_Query]& amp;season=$INFO[ListItem.Season]& amp;episode=$INFO[ListItem.Episode]</value>
</variable>

Anyway, unfortunately that's not the problem
