I've move JRiver (V21.0.76) to being our sole media solution and it is all going well with one exception. The exception is the occasional crash that seems to happen when deleting a recorded TV show or leaving a recently watched recorded TV show. Logs have been sent to to the usual support email.
Edit: Running Windows 10 with Digital TV Tuner PCIe Card and shows recording in .jtv onto a local solid-state drive
