Is there a specific video player I need to install to be able to see video in the CloneBD preview window? On my six year old PC, with a 3rd gen core i5, I can see video in the preview window. But I recently setup a new Dell PC, with an 8th gen Core i5. Clone BD works great, but the preview window is blank. I am not doing any transcoding. I've always used the lossless audio and video option when creating an MKV.
