A user has requested a DVD-ROM drive be added to their desktop PC so they can watch videos sent in by vendors. You only have a Blu-Ray player in inventory. Is it likely you deploy this to the user and meet their requirement?
The Blu-ray specification recommends but does not require backwards compatibility with DVDs. However in practice most Blu-Ray drives are backwards compatible with DVD discs and can play their content. You should check to be completely sure, but it is true that the likely scenario is your Blu-ray player will support DVDs.
