I have many dvds which I have copied as .iso files onto my external hard drive over the past few years & using win cd emu has allowed me to view the films without physically changing discs however since having to do a clean reinstall of my windows 10 home operating system along with a newly downloaded installation of win cd emu the same dvd .iso files mount but will not play. when opening the disc image it still shows the Audio_Ts and Video_Ts folders. I cant work out why.
