I applied the cff explorer fix and ran into the exact same problem, audio out of sync after 2 minutes.
Before the fix, it would crash when I tried to render to 1920×1080 .m2ts file. After the fix, it render quickly and looks like everything is working like it should. I render a 9 minutes file and found the audio out of sync after 2 minutes. No problem rendering it to wmv in 720p format.
System spec:
Win 7 home premium 64 bit
Athlon X4 945 (3.0 GHz)
8 GB memory
1 TB Seagate 7200 rpm.
Anybody find a way around it?
I will now try and render to other format. I’ll try it at 1440×1080.
