iTunes Extras on iPad, iPhone, Apple TV

[Photogenic]

I've given up discs for iTunes digital copies and have amassed a collection of over 300 movies. All of these movies can be played on my mobile devices and TVs, but for some reason, the iTunes extras included with almost every major title can not. To watch these special features, you need a Mac or PC.

Does this strike anyone else as being unusual? Apple's biggest products are by far the iPhone and iPad and customers are probably still more likely to watch iTunes videos on their Apple TV over their Macs or PCs. Heck, I don't even own a Mac or PC. It seems natural for the extras to be accessible right along the feature on the devices most customers are using.

In fact, I even emailed Tim Cook about this to ask that this be implemented. I find it sort of baffling.

Is there any explanation for this?
