I am a noob and sorry for the simple question. I created a decrypted backup of my disc with MakeMkv. It played fine through the Media Player. However, Home Theater 4 could not see the new title (I placed the folder in the same folder that HT4 is set to scan). Here is the directory structure. \\NAS \Movies \Halloween (1978) \BDMV \Certificate \MakeMKV All other MKV files under the Movies folder were detected and matched fine. Thanks.
You can also use Disc Utility to create .img files and rename to .iso. This way, if you ever used Win based software (why?), you can.
