Hi Leon...
Marc is correct - you will need to transcode your DVD's to something the TV can understand....and so begins the slippery slope...
Depending on the TV, the file type and the way that the video is encoded may need to be different. If you have a fairly new one (ie less than 10yo) made by a well known brand, they will look for .mpg, .mp4 and some can even find .avi. (both my LG's see every type)
If you have a cheapy bought from a German supermarket chain, they may or may not see the files (i speak from experience)
It can get a bit complicated from here, but stick with me - i've backed up my entire DVD collection, so.....
I have played with all the mentioned bits of software, and some are better than others.....
I would have recommended Freemake if you are a novice at this - if you selected one of the default options, it would encode the right format in the right container, and it just worked..... These days don't touch it with a barge pole. You had to be real careful when installing - they made their money side-loading other software that you didn't want unless you opted out (which was not easy) and now there are limitations on length of video, and a watermark unless you pay to have it removed.
DVD decrypter is the next best - it is also crippleware unless you pay for it.
Handbrake is great - and as you are ripping your own DVD's will work just fine....but....there are a lot of options to select so its not real easy to use...and big BUT.....you need to make sure you pick it up from the right place or you will end up with spyware or a virus. (

It does have encoding presets - so try some and see which works on your telly.(any of the 'Apple' presets should work)
DVDshrink is another(

It is pretty old, but still works. It will only encode to mpeg2 - so does not compress the video as well as say mp4 does . Good news is that mpeg2 is what the free to air stations transmit to - so you'd almost be assured it will be readable by your telly.
cheers and good luck
