This is the program for ripping DVD to the computer:
http://www.softpedia.com/progDownload/DVD-Shrink-Download-4128.html#download_locations
You have four locations to download from at the bottom of the page (all free), but the first two are not working, so choose
Softpedia Secure Download (US).
When you download and install, the rest is very simple. Run the program and put the DVD into drive. Choose 'Open disc' option. It will be analysed, the disc (takes couple of minutes) and then it is ready to be ripped. Click the 'Backup!' button (it's on the left of open disc button). You will get the small window with different setting options. As everything is already set you dont have to change anything, you can only change the option 'Select target folder for DVD output files' (if you want to change the place where you want to ripp the dvd to), but no need for that either. Remember that location where it says the content will be (it's usually D:\<name of the dvd>) so you can find it when it's done (this because I usually forget to look and alaways have to search for it later). Also make sure there is enough space on your computer for the content (you have that information below the "Select target folderf or DVD output files' note). At the end, click OK button and there you go.
If you wish to convert to another format after ripping use this program, it is easy:

(scrool to the bottom of the page and choose any download)
You have to open the program, choose the output formats you want, dragg and drop the files you want to convert to the window at the bottom, check the square fields beside the name of the files you wish to convert and click 'Encode'. Watch the audio format settings as you have to set them too for the videos. If you want a smaller file choose .avi in 'Select the output container', DivX in 'Select the output video codec' and mp3 in 'Select the audio output codec', and the option 'DivX - all players compatible' in a pop-up window before starting to encode.
If you should need any more help, just ask, I'll reply if I know.
Edit: Also, I forgot to mention, in the window for setting the options that appears after you click backup, uncheck the square field beside the note 'create audio ts and video ts subfolders' (this is at the bottom of the window).
If your DVD consists of several chapters or parts (or similar) you will get a ripp that also has those parts, not one coherent file. You will also get some aditional files which are not important for you. When converting to another format and later uploading, only choose the files that are the parts of the concert (or something else, if you should do this in the future with another dvd's). Those are parts (files) that are of the type 'DVD Movie' (they have a notably large size).
