I have a lite-on DVD writer LH-20A1P it worked fine up till about 2wheeks ago , I can read and write any type of cd (cd-r ,cd-rw) the problem is the DVD part , I can burn DVD’s ,video , data (DVD-R , DVD+R,DVD-RW) but it does not want to read the disks witch I had just burned,(I can read it on my LG DVD Writer), but if I watch a original DVD Video it does not seem to have any problems , it won’t boot from a burned DVD boot disk but ,it boots up from my original Windows Vista DVD , so it seems I can use original DVD’s but not burned DVD’s , firmware are up to date ,lens is clean ,everything is just the way it was , it just started this problem for no reason . Any answers?
