i work as an editor and in professional studios the standard is Avid. I reckon its products might be too expensive for home editing, though there is one great exeption: avid dv xpress free, which u can download on the website for.. euh.. free. I never used it but i heard good things about it. It might just do what you need.When i started in this bussiness i used adobe premiere.. though it is more basic than avid software, it does quite a lot.
