IF you had an external HD connected to a Blu-ray player you could. IF you had a Blu-ray player that was Wi-Fi capable you could network it to your PC and stream them from there.

These are the only two ways I know aside from burning the discs and watching it in a Blu-ray machine. One can create the AVCHD file structure with tsMuxeR then burn to disc with imgburn UDF 2.50.

If it's already in the AVCHD structure then you only need imgburn & UDF 2.50 to finish it off.

Nero will do it, here is an easy tutorial to follow. It worked wonders for me.
