Easiest way to edit audio in a ripped DVD file

[dmjerbear]

All I want to do is take a DVD and make a video file with a few words bleeped out / muted. I don't need to burn to another DVD, since I just play ripped moves on my PC anyway.

So I guess I need to know what format to rip to, and what program(s) to use.

Many thanks!

Rip the DVD to the hard drive using your regular decrypter/ripping program. Demux the audio, video and subtitles using PGCDemux. Import the audio stream into Audacity (you'll probably need the ffmpeg library installed for Audacity as well). Mute the sections in Audacity and export as AC3 audio.

Use the edited audio with the original video stream and subtitles you got from PGCDemux and import them into a DVD authoring program to make your new DVD. Muxman should work. You can also use AVStoDVD for this, since it won't re-encode compliant streams. For AVStoDVD, import the video first, then right click on the video stream when it shows up in the main window of AVStoDVD. This brings up options where you can import the audio and subtitles.

Can I combine the edited audio and video to an mkv somwhow?

Yes, you can, using MKVMerge GUI...found in MKVToolNix. The resulting MKV will have mpeg2 video codec and AC3 audio. Don't know if that is what you want. Plus it will still be the same size as the original DVD.

If you want it smaller, and with H264 video, you'd have to re-encode with something like VidCoder or Ripbot264.

Be sure to test the output each step of the way and make sure you haven't introduced any audio/video sync issues. Probably won't, but it helps to be sure before moving on to the next step.
