I have a Lite-On LH-20A1L that I've been using without problem for awhile now. Instead of following the "if it ain't broke, don't fix it" stance, I decided to update the firmware from BL01 to the latest BL05. Since then, it no longer works with Verbatim DVD+R Inkjet Printable disks. When I put one in, any app I use says the DVD is full with a single track for the whole space. All the other DVD's I try work fine including Taiyo Yuden, cheapie NexxTech's and even cheaper CompUSA generics. Only the Verbatims do this now. Any ideas? Can I backlevel my firmware without causing problems? Thanks!
