Hi PA - how ya doing ?
Trust you to bugger up ImgBurn So are you sorted now or still having bother ? I assume you haven't fiddled with any settings on ImgBurn, if you have restore the defaults.
Build mode - have you sorted this now ? Corny has done some cracking guides, but its quite straightforward, if you have a video_ts folder. When you open ImgBurn, select Build mode from the Mode button at the top.
Once in Build mode, select the folder icon and browse to where the video_ts folder is on your pc. Then you need to ensure that the output will be burned to disc ( I think you have this bit already), before you click burn just check under the options tab (top right of the GUI) that the file system is ISO9660 +UDF and then under labels tab you can insert your own title in the volume label sections. Check the verify button and then click to burn.
Any problems let me know !
