I am looking for a video editing solution that will allow me to edit a commercial DVD without audio & video degradation from being forced to convert .ifo .bup files etc. to .avi or .mpeg etc. Is there anything that can edit the .ifo .bup files etc. natively? Entry level video editing programs, such as pinnacle Studio 10 etc. don't allow this, I understand Adobe Premiere doesn't either! Your experience & insight would be greatly appreciated!!!
