help with nero please - newbie

I am new so please bare with me. All I want to do is download my movies from limewire and put them on a dvd. I use limewire but can't seem to get quality movies most are from cameras set up in theaters - how can i get good copy? I use an hp 840 writer but seems to take forever and sometimes burn process fails? what speed should i use? what dvd media should i use, i.e. dvd-r or dvd+r? then there is this ratio thing 4:3 and 16:9, what is this? what do i use? please help!!!!

 

Download a program called bitzi, from limewire, locate movie, right click, go to advanced, look up file with bitzi and it will then show you whether the d/l is genuine and have some comments.

I then burn these files using NeroVision as per my basic guide here
