I use this thing: http://www.amazon.com/Samsung-External-Blu-ray-SE-506CB-RSBDE/dp/B00JJGFRIQ/ref=sr_1_1?ie=UTF8&qid=1452194478&sr=8-1&keywords=samsung+blu-ray+writer

But, to be clear, this is for writing to blu-ray discs! (BD-R).

In your other post, you want to write to DVD. IF that is true, and you do not want to buy a blu-ray writer, you download the AVCHD versions and burn to DVD9 with a dvd burner and play in a blu-ray player that supports AVCHD (many of them do).

If you want to buy the blu-ray writer, and a few BD-R discs, you’ll end up with somewhat better quality and the ability to play on any blu-ray drive.
