I want to play more then 1 HD video at same time. How can I do that?
Play with more media players, that's can be much more easier.
If you would let us know what media player you are using, we could offer more specific details on how to play more than one HD video at a time. Many media players have a setting to allow more than one instance of the media player to be running at a time. It would be in the settings/preferences. VLC, GOM Player, MPC-HC, etc. are great media players that have a setting to allow more than one instance to run.
I think Both VLC and GOM players support this feature
for windos media player
Run Multiple WMP
Need more details here:
Are you wanting to play them on the same computer? Same monitor?
Do you want to output each video to it's own display?
Are they streaming from the web, or saved on your computer?
Basically we need to know more about what you are trying to accomplish and why.
