The movies, music videos and TV series purcahsed from iTunes Store are encoded by DRM protection which prevents you from editting the videos directly. However you can edit iTunes Video in NoteBurner M4V Converter Plus directly.
I have ever been in that case. I purchased Spongebob seasons from iTunes Store. I'm kind of disappointed they only come in blocks of two episodes like they show on TV. If possible, I would like to cut the video file into two separate episodes and edit the theme song and ending credits because it becomes repetitive.
Conventional video editors and video converters do not work for iTunes videos. My friends recommends NoteBurner M4V Converter Plus for me. It combines the features of DRM removal tool and multi-format video converter. It turns out to be an easy job to edit iTunes videos with NoteBurner M4V Converter Plus.
