I think that given the choice between VLC and Media Player, I would prefer working on Media Player, which is much more integrated into Haiku, and uses the kits instead of its own libraries. Ideally I would add some simple UI functionalities, then some basic video and audio functions, and I would love to make it work with some online services, like Last.fm, or Spotify (though that would be kinda hard)... I don't know how long that would take, but I wouldn't mind having a go at working on Transmission, though it's looking like quite a lot of work. Anyway, I'm glad that I can work on projects which interest me and contribute to improving Haiku.
