I dont see why people care what version the release come in, be it iso, img, video_ts, or any other format that I left out. It is not to hard to go between them.
If you dont like iso use winrar to extract the folders.
If you dont like folders get imgtool to make an image file.
For other formats you could get Daemon Tools to mount the image and copy with your burning software.
Personally I like video_ts folders, have had problems with dvds burned from iso. When reburn from folders extracted with winrar the dvds works fine. Personally i just like to get the releases, begger cant be choosers.
