Hello
As you I am sorry that Corel has abandoned the coding and decoding AVCHD 3D clips Sony TD10,20,30 camcorders.
I have the TD10 camcorder and I worked around the problem using a 3D MVC 3D HDTV converter software in Side by Side. Once the clips are converted to side by side, you can work in 3D.

What we can not do is export to MVC on blu ray and this is a shame. Question of 2D / 3D compatibility.By cons you can still make a Blu ray side by side compatible with your TV
