If they were you own creations fine then you would be the copyright owner.
Srictly speaking it is actually iffy about recording anyway but this is blind eyed for later personal viewing.
You probably could have sold them as used tapes, but then how would you word it to get a sale without raising the evil eye. Considering eBay is getting a lot of corporate stick over their easy going approach "we are only a venue" from major companies now they were probably glad to have caught out small fry like yourself (no offence intended) to say we are doing something about piracy etc.
It is easy for them to 'catch' someone like yourself making a mistake than catching major fraudsters who make a fortune.
Hard luck, once again eBay's slow response netted them your insertion fees as a bonus
