It seems that the reason it crashed was because i didn't use proper settings. I tried again with different settings and it didn't crash. But I had no video, only audio. So I think I need to get the proper settings for converting MKV to AVI for it to work. Unfortunately, I'm new to this and don't know where to begin. What size, audio driver such as acc or mp3, etc, avi hd 264 or avi common, video driver such as divx or xvid, etc. I believe once I get the proper combination it should work.
I am also new to DVDFab. These are my settings:
Device = avi - generic.avi.divx, audiocopy
Output Type = video + audio
Fixed bitrate = 1056
Frame Resolution = 720x306
Frame Rate = 23.976 (I think this is US standard, not sure)
