Teo En Ming, instead of uploading the new changed files, we need "patch" 
files showing the differences between the original and changed 
versions.  This allows us to see where you started (i.e. revision of the 
original file) and what changes were made.

The easiest way to get these is by using SVN to create the patch (or 
"diff").  Once you check out a working copy of the source (as described 
at http://svn.mythtv.org ) to your local hard drive, make the desired 
changes and then execute the following command from the top level of the 
source tree (i.e.  in this case--since the changed files are in the 
"mythtv" repository--from the "mythtv" directory):

svn diff > ~/mythtv-singapore_frequency_table.patch

(which redirects the output of "svn diff" to a file in your home 
directory called "mythtv-singapore_frequency_table.patch").  Or, if 
you've made other unrelated changes to files in the working copy, you 
can be specific about the files you "diff" with)

svn diff libs/libmythtv/frequencies.c > 
~/mythtv-singapore_frequency_table.patch


If you're not using SVN, you can still make the patch, but you'll have 
to make a copy of the original file and get a difference between the 
before and after files.  For example, I would use:

mv libs/libmythtv/frequencies.c libs/libmythtv/frequencies.c-orig
cp !$ !:1

(This maintains the date/time on the original so that the edited file 
has a newer time in the patch.)  Then change 
libs/libmythtv/frequencies.c and execute the following from the mythtv 
directory:

diff -Nau libs/libmythtv/frequencies.c-orig libs/libmythtv/frequencies.c 
 > ~/mythtv-singapore_frequency_table.patch

Note, however, that the patch should be against SVN trunk--the current 
development version of mythtv.  If you're not using SVN trunk, but are 
using 0.19-fixes, it should be close enough (in this case) and I can 
help you get a patch against trunk.

If you're using mythtv-0.19 (downloaded a tarball from the website--and 
it looks like you are because of the changes to backedsettings.cpp), I 
/highly/ recommend you download 0.19-fixes (as described at 
http://svn.mythtv.org/ ) and make a patch against that version using 
SVN.  You'll also find that your MythTV will work /much/ better (there 
were some important fixes in 0.19-fixes that you don't want to run 
without ;).  If you can't do this, please let me know and I'll modify 
the patch for SVN trunk, but--for your sake--I really think you should 
upgrade to 0.19-fixes (where, since you'll be using SVN, it will be easy 
to make a patch).  And, since you're compiling MythTV, anyway, it should 
be a simple upgrade.  :)

Thank you for helping out with MythTV.
