(I) Unplayed Audio Podcast smartlist that plays 100 audio unheard unskipped podcasts starting from the earliest added.
Podcast is true
Play Count is 0
Skip Count is 0
Kind does not contain MPEG-4
Limit to 100 items selected by least recently added
To create a Video podcast just change the Kind parameter on the smartlist to "contains"
You can sort the list so it will play by artist, album (most Podcasts have album names consistent), genre etc
Setting Video Kind to Movie admits most video podcasts however others get filtered out - so avoid this parameter.
