I'm just testing a spare box out I have here, for some reason if I use the Vix image (latest installed)
It will move my motor a few times and then stop. I have to reboot the box to move the motor again or get a lock.

On other images such as OpenATV I don't have this issue.

This setup also works fine on my DM800HD and my TBS 5520SE.

Only with this box when using Vix I get this issue, but I would rather use Vix than the alternatives that work
