I recent excitedly upgrade to OS X 10.9 Mavericks. One of the biggest problems is the MPlayerX crashed on Mavericks.

Thanks to its open-source, I checked out the source.

So, the problem is that a value was used before it was initialized, and it was divided as zero. It’s the time slider’s max value, being used to calculate the knob.

The patch is here, also I committed some possible fixes in the repository.

The workable version can be downloaded on Copy.com, or MediaFire, with the dSYM.

Update The author has updated it, please download it at MPlayerX.org.
