Generation loss — quality may degrade
M4V uses lossy compression, and so does VOB. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Some metadata may not survive
Your M4V file may contain MP4 atoms, iTunes tags metadata. VOB has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
What compression artifacts to expect
VOB lossy compression can produce MPEG-2 blockiness. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.
About M4V to VOB Conversion

What Happens When You Convert M4V to VOB
Your M4V video is transcoded — video and audio streams are decoded and re-encoded into the VOB container. This is a lossy process that takes time proportional to the video duration.
Your M4V file is demuxed — video, audio, and subtitle streams are separated
The video stream is decoded frame-by-frame, then re-encoded with VOB-compatible codecs (typically H.264 for MP4)
The audio stream is decoded and re-encoded (or copied if the codec is compatible)
Subtitle and chapter data is preserved where the target supports it
Streams are muxed into the VOB container and the file is saved
