When you use the "convert again" option in the Process Queue it will create another FLV file and leave the old one there, This is going to leave to a large amount of unused FLV files taking up space. When the FLV file gets converted again could it use the same name? or at least delete the old file and use a new name.

Also could you stop it from setting the "Added on" date to the date it was reconverted and just leave the old date. For example if a video has been on the site for a month and has comments etc but i decide to reconvert it for whatever reason it would say it was added today but the comments would be from a month ago which wouldn't make sense.
