So, to be clear, if I all I need to do is add XDR as a 4th player to my existing playercorefactory, making sure it points to XDRFE.exe (once it gets put in the directory via your app), all 4 players will show in 'play using' including XDR? If so great. Comparisons are only a couple button clicks with no hassle. The player setting is going to change when XDR is used and revert to default when it's closed to allow madVR subsequent playback use default settings. Now I understand. TIA.

MPC HC and MPC BE at the same time from the desktop for testing one title is also a good idea. Then one can retain a simulated .cal setting without affecting the other.....

I withdrew support for mpchc so when you setup mpcbe simply in the playercorefactory items looking for mpcbe replace the pointer to xdrfe.exe.

Example: (Your path to mpcbe) change to (path to xdrfe.exe) xdrfe is a front end that loads ALL movies passing arguments to mpcbe directly. You only need one player shown in external players call launch mpcbe or name it Launch mpcbe XDR whatever. your external players change mpcbe to xdrfe.exe. This will load xdrfe and check if cal file is present. If not it will proceed and shut down xdr wile letting madvr take over. hope this makes sense. Leave mpchc alone. At the end you should have 1 entry for mpcbe and 1 for mpchc and one for powerdvd17 whatever......

In xdrcontrol panel you set the path to mpcbe. This is stored in the regristry and called by xdrfe.exe to launch all instances of mpcbe64.exe
