I've got a routine of extracting downloaded video files, appending subtitles where required and moving them to the server that my PS3 connects, so I can watch it on my TV. This process involves about 3 steps, 1-2 minutes waiting, worse I have to be in front of the computer (second floor) to do these.
This weekend I decided to put an end to my misery and developed a small application which watches a folder and carries out defined rules based on the created/renamed files in the folder. After about 2-3 hours of hacking I end up with Psycho Folder. Just modify the Rules.xml, define your own rules and let it do the job for you. After I saw it on action and really liked it and spent another couple of hours for polishing.
