[QUOTE=chef;2499094]DVD were renamed to Digital Versatile Disc a while ago. 
The issues with error correction etc. got overcome when they entered the “computer usage area”…[/QUOTE]
DVD+/-R RW renamed “versatile” under ISO format with limited editing capability,Video cameras didn’t have a lot of editing capability then so it wasn’t an issue. The name was changed to reflect how consumers were now using the format regardless of intended market of use for video cameras.UDF improves editing with better camera capability but still designed for the type of large file a video camera would produce.Video cameras have no hard drive with optical disc so the editing changes are made directly to disc.Intro’s and end credits are the typical edits and where the discs wear out first.Not an issue with a computer since any edits are made to hard drive then archived to disc after changes are made…Although improved editing capability,many still complain about UDF small file handling and sometimes not being able to delete.
Regardless of name change or revisions made in UDF to improve editing from ISO filesystem, it’s still intended for large video files(you can dress up and change the name of a dog,but it’s still a dog).ISO and UDF filesystems created for discs without Sectors (DVD+/-R RW ,why you need the special software).
DVD RAM has sectors so it could use the computer formats handling computer types of files=youtube size video, mp3 audio,documents.
So which format and file system to use depends on how you plan to use the disc.
Using UDF on a DVD RAM somewhat defeats the purpose of having sectors but many video cameras began using that format because ISO’s editing wasn’t the greatest.Fact is since UDF was created many shooting video could switch to the cheaper DVD-/+ RW disc with UDF but their equipment doesn’t allow for the change.So the manufacturers recommend formatting the discs with UDF to handle in camera editing better.
