What is the codec that "aXXo" uses in his movies? GSpot says that it's DX5.0/xvid. AVICodec and FFDShow says it's DivX5.0. Is it somekind of hybrid of DX5.0 and XviD?

DivX and Xvid both produce MPEG-4 ASP video.

Those tools just read the FourCC information from the file. The FourCC indicates which encoder was used. Common FourCCs are DX50 and XVID.

Based on the info you give I would say the encoder that he uses is DivX (not necessarily version 5.0).

I thought aXXo used x264?

lol, not yet. He uses Xvid but uses a Xvid profile and changes the FourCC to DX50 so the files can play on stand-alone players

Be careful:
FourCC != Codec != Video Format

Exactly the same video format can be produced by different Codecs/Encoder.
For example MPEG-4 ASP can be produced by DivX, as well as Xvid or libavcodec.
So don't mix-up Codec and Video Format ;)

At the same time FourCC's are not reliable at all!
The same Encoder might use different FourCC's and the same FourCC might be used by different Encoders.
Also possible that somebody overwrote the FourCC manually...

Thanks!
