there is already a way to MANUAL record your games....

Here’s how to do it:
When you’re in a game go into the console (Ctrl-F8; same to exit) and type “replayrecordstart <filename>” (filename can be anything, for example replay1.rep)
Once you’re done recording type “replayrecordstop”. It saves the replay into your user files folder, under linux it’s ~/.Heroes of Newerth/game/replays. Under windows it puts them in ‘Application Data’ or ‘My Documents’, so you have to move the replay file into your root game folder where the HoN executable file is (hon.exe or hon-x86).
After that, to play the replay you have to go into a practice game and type into the console “startreplay <filename>”.
