Download MVS Player, to open many videos simultaneously
MVS Player (=Multi Video Screening) is the only one (so far as I know) Multi-Video Player.
It is able to open and play up to 12 videos simultaneously, DivX / XviD compliant.
MVS Player is very fast (15 ms for a video of 1.4 GB).
It supports SuDivx – Xvid – MPG – MPEG4 – AVI – WMV video formats.
