WINDOWS 7 can not read DVD-R data disks.

I have had this problem for years and so have many others, but no one seems to have a serious or functioning solution. I will upload some screenshots so that those of you with solutions can see what faults lie within the system and ways to correct the settings.many times the cd disks will show the files, but the DVDs will not. Some of my dvds that I can see who the UDF component,perhaps the disk was not burnt wile including the UDF reader, but if I need to install a UDF reader to my system will that work? Please look at the registry and other images , (yes ts an vintage machine) but it is the one that I used to burn the original disks. cd not reading registry.jpg cd not reading registry.jpg disk burner drive.jpg .
