My pc wont read dvd's burnt by the dvd burner

when i burn data or movies on dvd media with toshiba sd-r5112 with nero ,i can play them on my home dvd player but when i try to play them on my p.c i get the message “the disk in drive … is unformatted”
this problem started after a severe crush of my pc which made me install the operating system from scratch
i have no idea if the burner is the problem ,software ,what ever
any help would be appreciated

ok here we go

  1. update your nero version, will give you better burns

  2. update your drives firmware (though i couldn’t find any firmware for it)

  3. buy good quality blank media, then is your still having the same problem post back

i’ll try
