tomorrow i'm buying Verbatim DVD+R's, there more expensive but everybody says there the best, so i bow to their expertise, but i have a question and please excuse my ignorance, but i made a stupid mistake last time i tried to burn my films onto a DVD+R (Ritek), i had'nt converted to VOB; BUP and IFO files, i've now done that, DVDFlick did that for me and it created a VIDEO_TS map + an AUDIO_TS map, i've converted 3 films separately, put the 8-9 files, vob's, ifo's and bup's into an under map with the name of the film on it, if that's correct why do i need to create an ISO, secondly, when i open Imgburn do i click on "write image file to disk" or "write files/folders to disk" or does it make no difference? thirdly can anyone tell me why when i started with an Avi file of @700 Mb i've now ended up with a collection of files (vob, ifo and bup) that take up 4.1 Gb! i'm asking these questions because i can't find the answers anywhere, i've even googled it with no success, seriously confused and don't want to ruin the burn tomorrow through my own ignorance!!!
