I recently obtained collection of new sealed CEDs + unsealed mint condition probably unplayed CEDs.

If you see this note, the CED in the listing it is from that source.

I also have other CEDs from other sources listed.

I have working CED players and still watch movies. 

So all unsealed CEDs will be have been tested, I may not watch the whole movie if it does not interest me, but willl have tested some of it.
