I used a combo VHS/DVD recorder (a Philips DVDR3320V) to capture 50 VHS-C family videos on DVD. I understand they are already encoded in mpeg-2.
Will I loose quality during editing? I only want to cut out the bad parts.

If you use a "smart rendering" editor like TMPGenc MPEG smart Renderer or VIdeoReDo you will only have minor (basically unnoticeable) loss within up to a half-second of each edit. The rest will be passed through untouched.
Other tools like AviDemux can do it as well, but you are restricted to editing on keyframes.
Doesn't Adobe decompress MPEG2 material as soon as you import it?

I used VideoReDo to cut out some fragments. I'm really happy with the result. I seems like (almost) no quality is lost during the process.
However, I don 't know in which format I should save to benefit from the smart rendering (cfr list below).
I tried MPEG-2 program stream (*.mpeg) and H.264 MP4 (*.MP4). Apparently both give the same output quality.
Which is the best "future proof" format?
I burned both files on a DVD but was not able to play them on my DVD player that supports Divx.
Thx for your advice!
Almost everything else outside of the MPEG(2) family will be re-encoded thus losing your entire reasoning....editing with no quality loss.
DVD is MPEG2. It can be nothing else(OK maybe MPEG1). If you want your end result to be DVD....DVD/MPEG2 is the only output you need to worry about.
Also, the concept of smart-rendering is based on the intention of not re-encoding (or minimal, with those few exceptions being of the same format as the source).
