I tired restoring an earlier version of HandBrake from a backup but that didn't work either. That tells me something is probably missing but I don't know what.
Below is the partial log, copied while a scan was under way. The process goes on forever, and can't be cancelled during the scan so I have to quit HandBrake. I've installed the DLL for decoding, and checked the box in Tools > Advanced. Have I overlooked something else that needs to be done?
Thank you.
