Just a quick update, because I figured out how to transfer DVDs you already own to a Kindle Fire, so you can watch films without an internet connection.
Just before I go any further, if it helps, I'm running Windows 7 on my laptop, and have the 32gb Kindle Fire HD.
Here goes:-
1 Copy the DVD to the hard drive of your computer. I used Windows Media for this, all standard stuff.
The DVD will show up as a file in the 'pictures-video' section of your pc.
2 Use the USB cable to connect your Kindle Fire to your pc.
Click on the Windows icon, then 'computer', then double click on the Kindle icon to open it. Double click again on 'internal storage'. You'll see a list of the files that Kindle has, including 'movies'.
3 Drag and drop the DVD file to the 'movies' file. The DVD will copy over to the Kindle Fire, it takes a few minutes.
So far, so easy.
The next bit has taken me hours to work around...
When you go to the Kindle Fire and try to watch your film, it'll be impossible to locate it. In the 'Films' section of the Kindle, you'll be offered every commercial film under the sun, except the one you've just copied across.
What you need is an app.
I tried searching in the app store under 'personal video', as suggested by Amazon, and found several which could 'see' my video, but wouldn't play it.
Now, you might have to take a leap of faith, here... so proceed at your own risk.
On my laptop, I've installed the utterly brilliant, free, VLC player, which has got me out of so much trouble in the past by being able to play virtually any obscure bit of music or film I can throw at it.
The VLC player app for Kindle is free, but - and this is a big but - it comes with a shedload of BIG SHOUTY CAPITAL LETTER WARNINGS about installing it because IT MIGHT BE NOTHING BUT TROUBLE. So, I took a deep breath and installed it.
It works. I can play my video. Perfectly. It hasn't [yet] made everything else crash. I am a happy bunny.
PS I'll keep you posted - if you want to hang on before trying this out, I'll update this thread with any problems I find.
