I have come up against a brick wall trying to
find out if I can play .mkv format movies on my iPad. Some web sources say it
is can’t be done; others reckon it is possible but only by converting the
files, whilst others suggest that I need a special app that costs £5.00. Can
you give me a definitive answer?
Roger Fielding, by email
Playing non-Apple approved media formats is a
constant source of irritation for iPad owners but there are almost always
workarounds. In this instance I suggest an excellent free media player called
VLC, which has recently returned to the Apple App Store after a complete
rebuild. It can play .mkv files, and many other formats not native to the iPad,
but one of the most useful features is Wi-Fi upload. This makes it incredibly
easy to transfer media files from your PC (or Mac or Linux computer) to the
iPad. All you have to do is switch on the feature in VLC on your iPad, it
displays an IP address, usually something like: http://192.168.0.5.7777. Enter
this into the address box on your PC’s browser and simply drag and drop the
media file you want to transfer onto the newly opened window. The only thing to
watch out for is that the file transfer will fail if you iPad is set to Auto
Lock so temporarily disable this from the iPad’s Settings menu until the
transfer has completed.
Our Windows 7 laptop spends a lot of time
updating Windows. Is there any way in which we can turn off automatic update?
Sometimes they seem to go on interminably, which doesn't seem right. Is there any actual advantage in Windows
being constantly updated?
George Mercer, by email
Yes, you can turn off automatic updates but it
is not advisable. Many of them will be minor tweaks and fixes for problems that
probably won’t affect you but in amongst the routine updates there are usually
important or critical security patches. These are meant to plug newly
discovered loopholes and vulnerabilities that could be used to infect your
machine, or allow hackers to get at your data, and those you do want. To take
charge go to Control Panel menu and click Windows Updates. The opening page
shows you the number of updates waiting to be installed, their relative
importance, whether or not they are optional, and what they are for, so you can
determine which ones you want. If you click the Change Settings link you can
decide whether or not to install them automatically, without consulting you,
install them manually, at your convenience, when and how often to check for
updates, or turn automatic updating altogether.
Some years ago following your recommendation
and installed a very useful program called SuperKeys, which provided for
shortcuts to any phrase, numbers or combination that one wished. A few weeks
ago I had to reinstall Windows and also tried to reinstall SuperKeys, but found
that a virus had corrupted the download. Do you know whether there is a clean
version of this program available or can you suggest another similar utility?
Terence Graham, by email
Of course an infected download is possible but
I suspect that the program has been wrongly flagged up as malicious by your
security software. SuperKeys interacts with and changes the way the keyboard
works. This similar behaviour to a type of malware called a keylogger, which
monitors keystrokes looking for PINs and passwords, and passes them on to
fraudsters. To avoid the possibility of downloading an infected file get the
program direct from the publishers website (http://goo.gl/seJkXi).
There are times when I want to convert an Adobe
Acrobat document into a Word document, but it seems the technology for this
costs money. Is there a free and easy method?
M Seager, Essex
Acrobat documents, more commonly known as pdfs
(portable document format) come in a variety of styles but if the ones you are
interested in originated as text documents then it is often possible to
highlight the part that you want and use your pdf reader’s Text Copy function
to copy it to the Windows Clipboard and from there Paste it into a Word
document. You may find this easier with an alternative pdf reader called Foxit
(free from http://goo.gl/J6oBC), which has
the Text copy option on the toolbar. However if the document’s author or
publisher has locked or protected it, preventing simple copy and paste
functions. Assuming that copyright infringement is not an issue then there are
several workarounds. The simplest (free) one is to print the document then scan
it using OCR (optical character recognition) software and convert what is
essentially an image of words on paper, into editable text. This trick also
works with pdfs that have been created from scanned images, providing the print
is sufficiently sharp.
I recently purchased a new printer, which I
have successfully installed on my Vista laptop. When I tried to install it on
my XP desktop a message appeared telling me that I needed to install Service
Pack 3. I tried to do this via Microsoft Updates but was unsuccessful. I
contacted Microsoft and they told me they could perform the installation by
remotely accessing my PC and that this would cost £65. As this was more than the cost of the printer it didn't seem
a very good deal. Is it possible to download SP3 for free?
Barry Boughton, by email
Yes it is and that Microsoft advisor should
have their knuckles rapped for not pointing you to the free manual download,
which is available from the MS site at: http://goo.gl/wrsbPA.
