How to record output from my computer?

FOR COMPUTER GENIUSES ONLY........... how do i record the output of a media player,?

• lets say im playing a avi of "batman" in it and save it as a file exactly the same as that avi of "batman" im playing in that media player... ok to be exact. in a nut shell ...the output of the media player im using ( Stereoscopic Player) is created by using 2 files , an avi(say of batman), and an avs file(basically a notepad file with some code on it saved with a different file extension (.avs instead of .txt). the purpose of the avs file is to convert the avi file of "batman" into 3d (red/blue type) and to make that happen, in stereoscopic player you open a avs file created specifically for the avi of batman that resides in the same folder as the batman avi instead of the avi itself because stereoscopic player uses that code in the avs file to open the avi automatically and convert it to 3d with out you even touching the avi file, as long as it resides in the same folder, well stereoscopic player doesnt have a record function . and since the 3d version of batman requires you to use those two files , you couldnt upload it on you tube cuz the avs wouldnt load and only stereoscopic player would convert it to a 3d movie anyway.. so how do i record the output of those 2 files, the avs and avi, that make up the 3d version of batman id see on my screen.playing in stereoscopic player as one file...i could then upload on youtube...(avi or mp4 etc..). i tried the screen capture type of software but the frame rates were too low and the quality wasnt that good....id like a low file size 2gb or less and comparable quality to what is playing in stereoscopic player....i/e dvd quality...
