Trying to replicate a view with no success
When you say, "autoselects/autodefaults the dropdown menu item based on the show name," what are you trying to do, exactly? What show name you are trying to auto-select? Is this view capable of showing shows with other show names? If so, and say you have ten shows in that list, which one do you want to be the default?

Are you trying to have links to that same view from different places in the site and you want a link on the Tech Guy page to automatically filter the Tech Guy shows, and a link on the Fictional Mister Podcast page to automatically filter to the Fictional Mister Podcast shows?
