One of the major advantages of the player is its Nero Digital support. The player is advertised as Nero Digital Standard profile certified. Below we can view the major specs for each Nero Digital profile:

For our tests, we used several files, both encoded and downloaded from the www.nerodigital.com website. For our encoding, we used as source, the movie Gladiator, chapter 19. We used the latest Nero 7.2.0.3b package, that includes the latest Nero Recode version. Using all available ASP profiles, we created several test files, with default settings. That included files with two Audio tracks (Main and Commentary) and two subtitles (English/Greek). This is valid of course, only for the Standard profile.

All tested files were playable on the Grundig GDP-3550, the Audio tracks switchable and the Subtitles were displayed perfectly. Both English and Greek characters were recognized, so this might be the only way to view subtitles in case your language is not officially supported.

The downloaded trailers from www.nerodigital.com also played perfectly. Please note that only ASP profile files are supported, not AVC.
