SMPlayer no long works with WinXP-sp1, and possibly Win2000. Qt 4.8.6 is the problem. Last know good is SVN r6257 with Qt 4.8.4.
"Faulting application smplayer.exe, version 14.3.0.0, faulting module qtcore4.dll, version 4.8.6.0, fault address 0x00125dfe."
Possible to revert to the last working version of Qt?
