To be honest, I haven't used Win. Media Player in ages, and even when I did, I don't recall ever burning from it. Before I go any further, I am sure you are aware that laptop burners are not the best and tend to flame out when it comes to continued burning. So, maybe when times get a little better for you, you could invest in a good external drive. But, back to the problem at hand. I would definitely forgo the burning using media player, instead I highly recommend ImgBurn. You can then simply add your files and burn as data to your disk. Be sure to use some high quality media such as Taiyo Yuden, Verbatim, or Sony as that can make all the difference in the world on the quality and longevity of your files.
