851s to 832s format disk dvd-rw, fail

I changed my 851s liteon to 832s, I tried to do a full format on a dvd-rw, it fails after 3.40 mins, the quick erase works fine. I like to have everything working as they were, or do I really need to do a full format on my dvd-rw for my re-writes?

i use dvd decrypter and it automatickly overwrites the dvd again and agian

A quick erase will do just fine. I seldom use full format.
