How to encode with Nero Digital?

How to play Nero Digital? As Nero Digital follows 100% the MPEG-4 standard you should be able to play the created .mp4 files with any player supporting .mp4 and the used codec (features), both hardware and software
Nero's own player is called Nero Showtime and is available in the same package as Recode2, available for free evaluation.
My favourite player doesnt give me Chapters, Subtitles or multiple audio streams?
After installing the Nero package this can happen, as Nero limits the playback of Chapters, Subtitles and multiple audio streams to Nero Showtime when using their directshow filters
In order to use other dshow based player, install either 3ivx (handles Chapters and multiple audio streams, but not AVC), Moonlight (handles multiple audio and AVC) or use a not directshow based player, like VideoLAN (multiple audio) aso...
Hardware playback of Nero Digital: As it goes for software players, also all hardware players supporting the .mp4 container and the used codec (settings) should play the ND files, as they are following 100% the MPEG-4 standard.
Still to avoid interoperability problems Nero created private MPEG-4 Profiles and the Nero Certification:
All Nero certified players should be able to handle
- MPEG-4 ASP video (most handle the "Standard Profile": not allowing QPEL and GMC)
- MPEG-4 AAC audio (with Standard Profile: AAC-LC, not multichannel, AAC-HE not with full quality)
- Chapters
- VobSub Subtitles
- 2 Audio streams
