Downloaded the update, 18.104.22.168. When I rip a DVD to PS3 profile, it screams through it. At the end, the CPU usage drops to zero but it still reports a high fps encode speed. I assumed this is the GPU still working, not the CPU. This winds down to zero, but then the job never reports that it's finished. I had to click "cancel" to stop it. The video was completely encoded.
This is a real problem if you're working on a queue of jobs, as the first job will hang the queue.
