ReactiveUI.UnhandledErrorException: An object implementing IHandleObservableErrors (often a ReactiveCommand or ObservableAsPropertyHelper) has errored, thereby breaking its observable pipeline. To prevent this, ensure the pipeline does not error, or Subscribe to the ThrownExceptions property of the object in question to handle the erroneous case.

Looks like the crash was from getting an empty result from a hb.dll call. It has to match up in terms of capabilities with the version of VidCoder/HandBrakeInterop.dll, so pasting in a custom version isn't always going to work.
