I can do a PHP overlay, and since you're running linux, what you are asking for is possible. However, what you are asking for is not going to be easy, and I can't promise the playback of DVDs or Manipulating Photographs or Sound Input, as that can't yet be governed by PHP, or any other scripting language out there (Actually, using browser plugins and ActiveX may compensate for that). I've done something like this before in a forum mod, and CD management and playback is not an issue. I think that the entire project will take about 3 weeks and is worth $250, as it has a lot of complicated modules. Unfortunately, your maximum bid does not go that high.
