SOHW-812s Liteon can NOT read dvd

I used 812s for 3 months. And it works great for burning CDs or DVDs. But one thing that bother me that this 812s can NOT read my Avatar DVDs … of course this not legit :cop: , but I dont know brand of this DVDs (avatar) coz it cover printed and there is no info in inner-circle of this DVDs. I already did firmware upgrade (from US0Q to US0S), but this problem still raise, this 812s can NOT read Avatar DVDs … please someone help … thanks in advance …


Does that Avatar DVD will play fine on your standalone DVD Player? If it does not play on everything, then the DVD is bad.

I can play it on my Pioneer DVD writer, and on my Sanken DVD Player.
