I was told DVD-R are much more sensitive to mishandling and one should not expose them to direct sunlight or extreme heat. I do not know if this is true or not but I heard long pauses is also not good for them because of the way the film content was burned on it. I find it very difficult to believe but is there any truth to this?

It is really hard to say yet about DVD-R's and their longevity. It is hard to tell the myth from the facts with all that is posted. I've read where some say not to use permanent markers on DVD-R's because of the chemical composition of the marker can eat through the top protective layer over time if it is not thick enough. Believe it or not.
I think it is straight forward that the ink substance within a DVD-R is affected by the heat of the laser when burned to imprint the content. But you can't burn it twice so it must go into some inactive state. But does prolonged exposure to heat mess with the content over time? Can the content degrade over time, faster then an pressed DVD? If so, is the time an issue for us (e.g., 5 years, 20 years, 100 years)?
I have DVD-R's I've made for my kids that start freezing and pixelating after a few years of use with no direct abuse to the disks themselves. But these have been viewed a gazillion times in kids terminology.
From what I've read from a study performed on DVD disks is that a DVD-R should last longer then we will ever need it to last if properly cared for. I also believe from personal experience heat can impact them orver time (players can get very hot internally and then their is the laser itself). So if you avoid contact with the content surface, avoid scratches and other types of abuse to the surface, keep them in their cases when not used, and don't typically watch them 100+ times each, they should last a life time. We will know better in 10+ years how these archive disks last.
Of course this is just my perspective. I'm not an expert in the field, so take it however you like. Maybe other will chime in with their experiences.
