There is a built-in cheat function that uses action replay codes. You do not use it to play movies. Instead you can use a homebrew app such as Moonsheel to play dpg movies.
there are a few other apps that can play videos as well.

Yes.

What other Media player plays .DPG on the Nintendo DS?
the maker of Moonshell is the maker or .DPG, the only format which can be played on
the Nintendo DS so far.
and also you broke a rule:

And I was imitating your one word answer, which you edited.

I don't believe that moonlight invented dpg. It's mpeg-1 video spliced with WAV GSM 6.01 with a custom header.

who is moonlight?
and yes the maker of Moonshell, the .DPG media player, did make .DPG.
The person made .DPG so that it would work on moonshell.

Moonlight is the creator of moonshell.
And he/she definitely did not create mpeg-1 video, mpeg layer 2 audio, or Ogg vorbis.

listen to arctic flame, he speaks sense.

Yes there is. DSMplay, which is by moonlight, the creater of moonshell, can play supposed psp quality videos. But the videos take up about 3x more space than a dpg.Yes, but not everyone uses it. (I deleted mine for more space.) If I'm not mistaken, there are a few other apps that can play videos as well.
