It's possible the BluRay "burn" laser failed in the drive. Hope the USB drive works out well for you...
I purchased an XPS 8930 SE in October 2019. I ordered the BD RE burner, Item #: 428-ABFD. Before yesterday, I had never attempted to burn a high-definition video file to a BD disk with the XPS 8930. The burner does play BDs and burns and plays DVDs. The description of the device on my invoice is: "BDRE Drive (Reads and Writes to Blu-Ray disks)." I am running Windows 11 Pro 22H2, fully updated. The Device Manager shows no issues "This device is working normally."  The driver is from 2006-06-21 by Microsoft, Driver Version: 10.0.22621.1. I manually checked for any Dell drivers on their support site, and none is listed. My attempts with both CyberLink PowerDirector 15 and CyberLink Power2Go to burn the video that I took resulted in the error message that says: "The Burning drive does not support this disk.". I have tried both Sony and Verbatim 25 GB Blu-ray disks. I never had a problem with the BD burner in my previous computer. The disks themselves are not to blame. I had to waste a lot of time to finally narrow the suspect down to the BD-RE drive. Either it is incapable of burning BD video; or it is defective, and for who know how long? The drive has not been used more than twenty times at most, primarily for burning updated boot disks to DVDs for my backup software programs a couple of times a year. I have successfully "produced" the video in .mt2s format and .mp4 format and copied those files to a USB flash drive.  Both play perfectly on my TV, so it is not a problem with the video itself. The computer is long out of warranty. I want to ensure that if a replacement burner is ordered, if available, it will actually burn BDMV videos. Otherwise, I guess I am looking at trying to find a BD burner that will fit into the small BD drive slot and can be successfully connected; or resort to an external BD burner, of which there appear to be very few and which are very slow. I burned dozens of video BD disks with the LG BD burner in my former Maingear desktop. That burner was a substantial size and reliable. I did not have to worry about producing "coasters.". The Dell BD RE drive in the XPS 8930 is very flimsy and thin. The slot is too small for me to be able to replace it with an LG BD drive. Of course, I would also have to worry about whether Dell has propriety plugs and cables. Any suggestions will be welcome. I need to be able to burn this Blu-ray video. Ten copies are requested. Thank you in advance. Have a great day. Regards,Phil
