Hi, I have, I believe, the same problem of issues #466864: When CCK field delete file does not work. and #481116: Removing a video and re-attaching it does not work when CCK options are in use that seemed to be solved (or maybe not?).
I set up the FileField fields to use instead of core upload sistem. When I upload the video all works fine. When I remove the original file with the "Remove" button and save the node, the original file gets delete but the converted file and the thumbnail remain on the system.

Even if you try to remove entire node the converted flash.flv is not deleted.
Comparing to matteogeco description it takes off the original file and thumbnail but the converted file stays in sites/default/files/flv .

I posted a patch in #481116: Removing a video and re-attaching it does not work when CCK options are in use, which works fine for me and when i understood you right, it maybe help you too.
