Once set up as you want it. this device is perfect - flawlessly converting formats. Great build quality too. If your use case is fit and forget then it's flawless.
If you carry it around as a general problem solver and have to grapple with the DIP switches then it can be frustrating working out what's on and what's off on the settings diagram screen-printed on the case. Could so easily be solved - although ideally it would have individual switches for resolution, frame rate, interlacing, etc.
