Yep, I can confirm that MinGW + Qt 4.8.4 (MAME dev-tools) on Win 7 x64 has an issue with MNG videos... oh man... the VC++ builds don't show this problem.

I just replaced the big MNG loading animation with a (much smaller) GIF animation in r5952 in the hope this would work with MinGW, but it doesn't... strange.
