Ive bought a toshiba SD330E dvd player and it wont playback my DVD+R and RW disc so I bought some DVD-RW discs and they dont play it says on my tosh disc error check disc, Ive tried a DVD-R and it worked why wont the others work

I am not sure I followed that, but I know that there are problems with different DVD drives playing competing media and sometimes playing media recorded on other drives. The -RW and +RW formats are the biggest part of the problem. Since they can't agree on which one will be the standard, not all disks play on all drives. Check the specs for your drive to see if it specifies what it will and won't play. If it supposed to be able to play all media, it may just be a bad drive.
