Some devices (like older Apple TVs) may require the NAS to transcode MP4 files if the audio codec (like 6-channel AC3) isn't supported.

You must convert the files into a format the DS can handle, typically (a specialized MPEG-1 derivative). What You Need A Flashcart: Usually an R4 Card or similar.

If you are looking for information regarding the app, the focus is usually on streaming performance and compatibility:

The gold-standard homebrew media player for the DS, capable of playing DPG videos and MP3/FLAC music.

Users often compare DS Video to Plex, noting that Plex sometimes offers smoother playback for high-resolution files.
