Okay, follow these instructions and see if it helps:
1.) Close OBS if it's open.
2.) Open the roxio software and get the roxio to display
3.) Close the roxio software
4.) Open OBS again and see if it works.
Weird instructions I know, but it basically resets an internal setting to cause the device to output with different encoders. There's no real choice for the time being without their actual API (which is probably proprietary)
