I converted about 50 dvd movies with Handbrake to m4v (H264) format. The conversion was done on a fast Win7-x64 Ult system, Playback of the new m4v videos worked flawlessly. Once copied to the production system (also Win7-x64 Ult) I realized that some movies worked without problem while with others MC15 crashed right after opening. As the event viewer displayed some error with a raac.dll I suspected some problem with Real Alternative 2.02 installed.
I then realized that the converter system had only MC15 and CCCP installed, while the production system hat MC15, CCCP, Real and Quicktime Alternatives + Bass filters installed.
So I deinstalled Real Alternative and voilą, no more troubles with m4v videos.
Now, I was of the opinion that to have a comprehensive playback of all media types, one needs to install all of the above mentioned programs. Is this still valid? Did anybody else have the same problems? Could it be that the products need to be installed in a certain sequence? I can imagine, no real alternative no real playback! I don't use the newest CCCP version yet. Thanks for helping!
