There are some newer optical drives that only need 3.5 volts to operate and that is for reading data and installing programs. When playing DVDs, the drive has to run up and maintain a constant 5400 rpm which takes power and is the main reason why a lot
of people are having problems in that area.
First of all, this is "NOT" a laptop and never advertised to be one. It is designed to "replace" a laptop for which there is a difference in that description. That means you can use it for general functions like you would with a laptop. It is not a gaming
machine. It is not a media center. It is a tablet with an attachable keyboard.
Windows 8, when released, the decoder/codec for DVD movie playback was not included. Microsoft did not buy the license for it like they did with Windows 7. Most people today are now watching digital media via the Internet and is no longer needed. Now,
I too also (like you) have a bunch of movies on DVD. I can watch those movies using my Asus DVD burner drive with the Pro 3 when using the desktop version of VLC.
I agree with you 100% for the lack of information for these tablets. In fact, you have to dig around to find the PDF version of the user guide for the Surface tablets. I also note that the over use of "replaces your laptop" generates a lot of confusion
and people thinking these tablets have the horsepower to do that. The CPU can handle it but the rest of the components on the motherboard cannot.
So, in your case, I would recommend to go to http://www.videolan.org and download/install the desktop version of VLC. It also has the codecs for playing DivX formats as well. You might find that "it" and your DVD drive will play your movies. I have watched
at least six movies with mine and not one glitch in playback. By the way, your powered USB hub is providing the needed power for you DVD burner drive.
