There is only one way Iknow of to stop a deleted or UnOwned card from being downloaded when it's
part of a playlist.
1) make a custom card image with a Deleted banner on the Image ( so you know you deleted it )
2) put the files axxxx.vhdtrailers and axxxx.vhdshows in the models folder
3) Delete all the other files from the Models folder.
4) rebuild collection
in the future you would only need to do 1) and 3)
instead of using the Delete feature of iStipper.
Because a fully downloaded card, already has those two files in it.
Any attempt to Play a deleted card, or UnOwned card, will cause it to be re-Downloaded.
if you own it, you get the full card, if it's unOwned, you get the trailers.
