Alienware X51 specifications suggest it has dual layer DVD so it can burn and read DVDs but it can only read Blue ray disc and not burn it.

How do I know if my machine can burn dual layer DVD?
Nero Info Tool
or Tools/Drive/Capabilities inside ImgBurn
Also a Tip ...
Single-Layer burning is less sensitive. If you must Dual-Layer, try Verbatim brand "DVD+R DL". When permanently archiving data, I use high-quality Single-Layer 4.7gb. Always use Verify option.
Are you burning data files or movies?
I still haven't the chance to burn a DVD DL (dual layer) yet, when I get the chance, I will close this thread with the suggested answers.
Thanks for replies, please be patient while I get the chance, it may not come soon.
This should do the job:
I've been using it for a while, works great on my computer.
It support DVD–5, DVD–9; DVD-R, DVD+R, DVD-RW, DVD+RW, DVD+R DL, DVD-R DL, DVD-RAM.
