look at this one review of the samsung in question:
---
Like most HD players, it is slower than the cheapest DVD player, but that is okay, we have come to expect it and that no longer bothers us.
The problem with this player is that it does not output Dolby TrueHD or DTS-HD MA in any way, shape or form. The closest it comes is transcoding the audio to plain old Dolby Digital or a somewhat better DTS. Wow, classic DVD audio performance at a Blu-ray price. The real problem comes from some studios moving away from PCM lossless audio to TrueHD and DTS-HD MA. These include Sony Pictures whose latest release announcements have TrueHD only and FOX who is releasing only in DTS-HD MA, which very few players can play properly at all.
