This holds true especially for BD's packaged with extras and commentaries on the same disc as the feature presentation.

I just tried to play my new West Side Story BD (that came in a factory box also with a DVD version and a separate BD marked EXTRAS) on Leawo BD player for Windows PC last night. Leawo lacks a title menu. About 5 to 6 minutes into the movie, I was suddenly interrupted by commentaries on the film!

Thinking the BD might be defective, I tried this same BD out on my Panasonic BD player and I was greeted with a title menu upon loading the disc. I could play Extras or Play Movie. I played the movie and it played back as normal, start to finish, without any such interruptions so it was the format of the disc that was not compatible with Leawo. The BD was not at fault after all. Leawo just can't handle it. That's all.

Stand-alone DVD or BD players do tend to handle disc media much better than player software for computers.

A set-top movie disc player is a piece of hardware and not 'virtual' like disc player software installed on a PC. It is therefore much more robust in performance. You can't beat real machines vs virtual machines performance-wise for playing hard (physical) media. Set-top BD/DVD players are purpose built and designed and supplied with firmware expressly for playing back optical disc media. Trying to make a desktop computer into a disc media player was an afterthought in the PC industry.

Leawo is freeware to download, install and use, however. I suspect paid BD player software performs much better.
