DVDs won't play after a short while

Greetings I am new to this sight but would like to know why my dvds wont play after about five times or just sit in a case not used? but wont play, but will play on my computer but not my dvd player to TV? Should i burn these slow speed with max error proof?

What media are you burning them on ?
It does sound as though you’re using cheap ones.
What you’re burning them on, and at what speed would also be handy to know.
