don't think Toast would have problem creating AVCHD disc that can be played back on some devices (ex. with Roxio Video Player on Mac, PS3 etc). However, there is no guarantee if it would work with Samsung-BD1600. You have to test it to find out.
However, if the disc plays on other devices but just not Samsung BD-1600, I would think it's more of a Samsung issue than software issue. Searching on the net for Samsung BD-1600 and AVCHD shows BD-1600 seems picky on the disc for playback.
