I do have 'Auto Change Book Type' option enabled in the Write tab in the settings.
I switched to 'Write' mode, and now I see the Tools -> Drive -> Change Book Type... menu (perhaps only after media was inserted). Invoking that it asks for the REAL drive type. Your post suggests that might be LG, however, this is an HP branded laptop. I went ahead and selected LG and for popup Change For I selected "Drive (for DVD+R DL media)" but then it says under current setting "Unknown (FAILED!)" and "Reason: Invalid Command Operation Code". Do I need to do "Advanced" settings?
I do notice that after inserting Memorex +R DL media that "Book Type: DVD ROM" appears on the right hand side which is fully quoted at the bottom of this post.
I thought maybe a firmware update might help and ran menu item Tools -> Drive -> Check For Firmware Updates... but it states current firmware rev is HQ04 and on OK goes to an empty web page: http://forum.rpc1.org/dl_result.php?kaj=1&...isces=GMA-4082N
How do I determine whether I have an older writer that has problems with OPC? The write I originally did worked fine for the verify, it just fails when inserted into the car's navigation DVD player.
