Deleted DVD file still on Menu

[len12121]

I am using the HD200 in standalone mode. I have loaded DVD's onto a 1TB drive. I then decided to delete a couple of them. When I select DVD's there appears strange named DVD's that when I choose play are one of the ones I deleted. The original folder is gone but a new folder appears with a strange name ( e.q. $RDF$wd). Any help is appreciated.

That's a new one...can you submit a bug report on that so we can get more information from you? http://sagetv.com/bugs.html

As a followup I could not see any other folders when the Hard Drive was connected directly to the computer. When connected to HD200 I found a $Recycle.bin folder that I could not delete any files in it even though the HD200 was letting me delete them from a menu. Push ok but file was still there.
I then googled $recycle.bin and found on the Microsoft site a way through CMD to delete this foldere. It worked. Now when the Hard Drive is connected to HD200 and I look at DVD's this funky DVD folders are gone and everything looks ok. Maybe someone more knowledgeable in Computers and Hard Drives can tell me if what I am doing should need to be done or should the HD200 not be looking into the $Recycle.bin on the Hard Drive. It seems from the Microsoft article that Hard drives keep their own $Recycle.bin, if so how does it ever get deleted?
