correct me if i'm wrong,but i understand dvd shrink can convert a dvd9 to dvd5 disc,yes? if this is correct then i need help. i need to convert all my 70+ dvd's to single vob files,and i dont want the resulting files larger than 4000MB. vob files will give me the dvd quality i want (divx,mpeg4 etc will not do in this instance). i did look at clonedvdmobile vob passthrough,but this setting wont,unfortunately,allow me to alter quality or bit rate settings to meet my target size of 4000MB. so i'm starting with casino royale,and i need to convert movie only (2hours18mins) to a single vob file which dvd shrink can do. in dvd shrink edit>preferences,i have selected a custom size of 4000MB. casino royale is 6754MB in size. under re-author,compression is set to automatic.casino royale is now at 6701MB. the indicator bar at the top is green up to 4000MB,the rest being red up to 6754MB. when i go to back up,it says "target size exceeded - the current dvd size is too big....etc". if i continue and ignore error message,it says "space required 6754MB" for the files. so how do i compress a dvd9 to dvd5 with dvd shrink to fit a target size of 4000MB?
