Well, any questions or stuff regarding creating bumps should be placed here. I myself have only made a few b&w text bumps joking around so I use MS Paint, Windows Movie Maker and Acid Pro to make them

However on a more serious level, for stuff like picture bumps and that I'd use Adobe Photoshop and Adobe Premiere in conjunction with Acid. When it comes to changing a bumps audio for whatever reason, I use Windows Movie Maker to turn the movie into a DV stream (for quaility reasons) and add the new audio to the video stream (switch them, really) using Cubase SX, and then I convert the video (the DV Video stream with the new WAV Audio stream) to DivX. I don't use the video as a DivX or the audio as an MP3 (or whatever other format) for quality reasons, since re-encoding (technically re-compressing) compressed audio and video usually turns out quite bad, there's a lot of loss. Well, anyway those are my suggestions, any other suggestions or any questions or whatever feel free to post them here.
