realtor

I am sorry for such a lame newbie question. I have backed up my home movies before and well ... not real sure what in the hell is going on. Dvd shrink (the latest version) backs it up onto my hard drive in its spefic file where it should go then I go Iimgburn and pick the file, in my case its named "burn vds" I open up the file and nothing happens with imgburn. When i go to double click it it shows me it is in ts format. what am i screwin up?
