LUMIX FT1 and AVCHD lite

I have Pinnacle Studio 12 Plus.

When I Capture video file from LUMIX FT1 and AVCHD lite, it shows it as

00000.MTS
1280x720, H264, 50 fps
Duration 3:08

it shows in the Edit time bar as the correct duration and shows 25x188 = 4705 frames in the make movie.

However it renders the video at double speed, leaving the sound at normal speed.

This is allowing Pinnacle to select Project Preference from first scene , 1280x720 25fps 16:9 progressive. I have tried other setting with no change

Pinnacle Live Chat just told me;

Pinnacle 12 Plus does not support this Panasonic AVCHD codec.

in some months ahead, it may

the included software enables burning AVCHDlite to a dvd which Pinnacle can read, it is an acceptable solution.
