Question: how do i play a dvd on my samsung windows tablet
Document: Does not have a manual eject button. Does not even have the tiny hole to force a manual eject either. Ejection depends on 100% software, so if your software fails you, say goodbye to your disc.This worked for a little bit, it was able to play DVDs, but when I tried a music CD it did not work, and my Surface Pro 2 tablet would not even recognize that it was plugged in and so I therefore could not even eject the disc.
I was looking for a new USB 3 optical drive and decided to get this so I could use the docking station ports with my Windows 8 tablet (Lenovo ThinkPad 8). Now that it is working properly I absolutely love it but it took a bit of effort to get to this point.The instruction sheet that comes with it doesn't say a word about software but there is a suite of software and drivers on the device that you must install if you want it to work properly.
It didn't autorun and I could only get it to work as an optical drive. I stuffed around with all kinds of things trying to get it to work without success. Then I tried it with my laptop. The autorun kicked in and once all the software was installed it worked well so I went back to the tablet and ran the software install manually with no problems.With that out of the way everything works brilliantly.
Using it with my tablet allows me to hook the tablet up to my monitor via HDMI, as well as my wireless keyboard/mouse and back-up drives via the USB connections, with a USB port left over for thumb-drives or whatever. The VariDrive transforms the ThinkPad 8 into a really useful little PC.The VariDrive also looks really slick and takes up very little desk space. It's rubberised base keeps it where you place it.
The software for this device seems to be a permanent install. So far I have not discovered a way to uninstall it.My advice is only get this if:1) You really have a need for the plethora of ports that it comes with.2) You have so much faith in your software that you don't mind having zero ability to manually eject.3) You don't mind the commitment of a permanent irreversible install.
The VariDrive works perfectly with a Surface Pro as it does not duplicate the ports of the VariDrive...USB ports being a non-issue. The Drive also locked and would not eject a blank CD. Strangely, the VariDrive has no manual eject mechanism....that's either a serious oversight in design or a blatant expression of design egotism by Asus. For the record the problems I experienced occurred with two VariDrives including eating a blank CD (i.e.
Stylish package. Everything works except the video. Took 5 days to get a response from Asus tech support, finally after 4 calls got  very capable help. Downloaded Firmware upgrades, utilities and twiddled bios on my ASUS laptop (which this product IS designed to work with) -- went from a black & white checkerboard pattern to a black and white vertical stripe pattern. USB items are slow to boot. A lot of $$ for this kind of performance. The video problem is well documented on the web.
If it wasn't for the poor documentation that I reckon is possibly the source of most of the issues mentioned here, I would give this 5 stars.
I've had this unit for a week now, and am pretty unimpressed. It basically is so erratic that it isn't worth using. It does not seem to work correctly with VGA or HDMI. When in use, the mouse/cursor become unsable, and the unit (and everything attached to it) keeps 'dropping off' - meaning constantly disappearing disk drives (risky!) and flashing/disappearing monitors and then constant unplugging/restarting to get anything working.
I use this unit with my Surface Pro 2. It is so much more convenient than the Surface docking station and less expensive too. I found using it to be very intuitive. It is physically small and thus convenient to use on my restricted space small desk. The extra outlets are a blessing.
