I have been given a few precious DVD disks from a mate that were recorded onto by a LG Multi recorder. The type with inbuilt HDD and burner. The multi recorder has died so I am attempting to retrieve the recorded dvd's onto a PC as files but the disks are showing as blank in my PC when they clearly contain data. Both my Blue ray ROM and separate DVD ROM give same results showing as blank disk. I'm running W10. Any ideas on what is needed to display files. If I can at least get this far then I have half a chance at re encoding to an Mpeg4 or equivalent type.
