Toshiba DVD with 800mb cd

I have toshiba dvd sd-c2512 and it can not read 800mb cd that
i burned with nero software.(it can see the file name but can not access it).

I can read it from the cd-r/w.

Test it at some friends/neigbours pc ; If it doesn’t work there as well it might ONLY work in your cd/rw

I tried it on some cd’s and it worked very good.

only on my toshiba dvd it did not work.
