#3542: Stuttering playback due to bad refresh rate detection.

 Some video drivers like Openchrome in VBE mode can return modelines with
 only zeros. This causes a divide by zero in the refresh rate calculation
 in videoout_xv.cpp and the playback part tries to use NaN as reference.
 This results in stuttering, unwatchable playback.

 The patch checks if there will be a divide by zero and defaults to 60Hz if
 this is the case. I checked the patch with the real refresh rate of my
 monitor, I'm not sure what happens if there's a difference in myth/real
 refresh rate.
 Best would be to have a more reliable way to detect the refresh rate if
 this value is really critical.
