Go to the Twonky User interface (port 9000 of your MyCloud IP address, e.g. 192.168.1.32:9000). Use the media browser built-in to the Twonky UI to see what Twonky thinks it has found. This will tell you whether it’s a problem of Twonky not recognising the media format, or your Blu-Ray player not displaying the media file for some reason. Twonky will only show media that the DLNA client says it can understand. So if your player isn’t declaring that correctly, or Twonky hasn’t detected the client type correctly (or the client type info is incorrect), then your player may not present all the files.
You will find some pointers to setting the Media Receiver type, and other aspects of Twonky operation here:
