Ok Megui just went crazy today. Heres what I've been doing:
I have a Hauppauge HDPVR and I've captured some TV shows with it in TS file format. I ran the file through H264TS Cutter to get rid of the commercials then ran the "_cut.TS" file through DGAVCIndex. Then I usually set up my avisynth script like so
Code:
AvcSource("****************_cut.dga")
SmoothDeinterlace()
Lanczos4Resize(1280,720)
Then encode it with Megui.
I'll remind you that just before the crash i had encoded 2 other episodes with all the same procedures flawlessly, now the next 3 episodes all crash Megui after 54.16%. I get a error message that x264.exe has stopped working. And windows tells me that ffmpeg was the problem.

I've uninstalled and reinstalled megui, avisynth and ffdshow and I still get the same problem. I also get this problem on my laptop running windows 7 ultimate 64bit, running Vista ultimate 64bit on my main rig.

I don't get it I never installed, updated or uninstalled anything while this was going on, anyone have a clue what needs to be fixed?

Thanks
