[NAME]  And try a different brand of DVDs too.  I've wasted more Verbatim DVDs using the same PLDS DVD+-RW DU-8A5LH drive in my XPS 8930 than I care to count. Won't recommend another brand because -at least for me- some batches of other brands work and some don't...  YRMV Win 10 doesn't have its own media burner built in, so did you get "Windows Disc Image Burner" from their app store? Dell may have loaded Sonic's Power To Go software on your PC so maybe give that a try...
I have a brand new 8940 with issues burning to dual layer DVDs.  Standard CDR/DVDs work fine.  The drive is a PLDS DVD +- RW DU-8A5LH with latest firmware. I'm using Verbatim 8x DVD+R DL and they work just fine in my older 8910.  I've tried a couple of different burning software and they all fail.  Windows Disc Image Burner reports error code 0xC0AA0301 and of course I've tried any logical suggestions from those searches.  Is it possible there is an issue with the "dual burning capabilities" of the drive itself or could it be the media? As mentioned, burning the same ISO on the same media in my 5 year old XPS works just fine.  It has a HLDS instead of a PLDS.  I've called Dell tech support and only option they provided was to transfer to another team for paid support.  What good is the 3YR warranty I have then? Already ruined 5 blank DVD+R DL testing so hoping someone else has experienced this recently and had other ideas.  Searching the board there was an old article about something very similar and their solutions was media.. which happens to be the media I'm currently using. Thanks, Carson
