Have a hand held Tascam recorder w/usb cable. Want to record some karaoke onto a disc after I download it from the recorder to my computer. Just don't know how to burn disc yet. Any help appreciated

Windows Media player can do it.

Try ashampoo burning studio free for a easier experience if you want.

1st check do you got dvd wr or its just reader. Get nero burner you can get it easily from any torrent site. Download it. It tells you process in steps how to burn cd. It will be like just copy pasting data and burn.
Or you can do it like copy your data paste it in your dvd writer and just write click and press burn or write option it should works.
