i have a mad dog multimedia 4 in 1 cd burner/dvd drive. every time i try to burn a cd it seems to burn normally, but when i go to play the music that i burned on a cd player it doesnt work. i tried all my cd players in the house and they dont work. the only songs that do work are the first half. say i burn 15 songs only the first 7 or 8 song will work. i used nero realplayer and a whole bunch of others. they dont work. i have a intel celeron 466 mhz processor 256 mb ram and 125 watt power supply. can someone please help me thanks.
