Guys, Believe me when I say I am new to this I've only had Busrt! working a week and managed to download 2 moives so far without problems (.Vob, etc) I then download a .rar file - unpack using Ulimatezip and find it's a .img file?? I was a little stumped until reading this thread but I now understand what I need to do... You need to re-encode using something like DVD-Crypter, although I use DVD shrink this picks the file up striaght away and encodes it into .vob files which Nero picks up burn to DVD, jobs a goodin. Reference the last 20 minutes I found that the tail end of a dvd i.e. the last 1/2 gig can sometimes be a little flakey programs such as Nero only burn to around 4.35 gib and miss the last 1/2 gig because of this I would suggest trying this and seeing if it helps. Real newbie - but all the answers are here Great site.. and thanks all..
