This goes along with my post below.

I was able to download a video from Vimeo. The video downloaded in .MP4 format.

Since I'll be putting it to (standard) DVD, I will need to add some chapter markers, then re-render it in MPEG-2 format.

My question is, will a re-render to MPEG-2 degrade the quality of the video?

Thank you.

Additional rendering using a lossy codec (such as MPEG2) ALWAYS degrades the quality.

Yes it will degrade the quality. Lets count the number of times the file has been encoded so far.
1) Was the original file captured via tape, if so it needed to be ingested.
2) The file was edited and rendered.
3) Uploaded to Vimeo where it was rendered again
4) DVD makers added and rendered to MP2

In short the DVD will be 2 - 3 heavy compression sessions from the original. Most certainly it will be squashed.
Do try to get the original

When you say "original," do you mean the original footage, before ANY rendering has taken place?

Someone else edited it, and I'm sure it wasn't in Vegas, so an edited version saved out as DNxHD. Would that work?

Or is there a better workflow?

Yes, I would tell the customer that re-encoding a Vimeo file that has already been encoded 2 - 3 times is not going to yield the best quality. If you could get the originals that were uploaded to Vimeo, that would be 1 generation better.

In the mean time, I would encode one of the MP4 files to MPEG2 and author a DVD and see if the quality is acceptable to the client. They might be fine with it and you're doing all this extra work for nothing.

Yes, it will degrade the quality Ron, but putting it to standard DVD
will be ok, you will still get bit of a decent result.
However when doing this, try not to add too much effects/filters to it,
cause then it will really show obvious signs of degradation.
