This is a full transcode rather than a container swap, because MPEG-2 is not one of the codecs WMV carries. Every frame is decoded and re-encoded as WMV9.
If the source has subtitles baked in as a separate track, they will not survive: WMV does not support embedded subtitle streams.
Alternate audio tracks are dropped, because WMV carries one audio stream where VOB allows several.
One practical gain here: WMV is streaming-friendly, so the converted file begins playing while it is still downloading.
Expect the bitrate to move from roughly 6.5 Mbps to about 6 Mbps at 1080p, and file size to follow.
Converting VOB to WMV means moving audio out of the DVD-Video (MPEG-2 PS) container, introduced in 1996, and into ASF, which arrived in 1999. The two were designed with different priorities, and that is what determines whether this conversion costs you quality, storage, or compatibility.
Developed by DVD Forum in 1996, VOB stores audio using MPEG-2. That codec choice sets the upper bound on what any conversion can preserve.
WMV, from Microsoft and dating to 1999, uses WMV9, VC-1 and plays natively on 1 of the six platform categories we track. That combination is usually why people convert into it.
