Hi guys, thanks for the replies. I appear to have resolved the issue, I'm not entirely sure exactly what I did that made it work. Dxtory didn't have an anticheat option I could see anywhere, so don't think it has one at all. Firstly, I reinstalled the latest Dxtory, I deleted the x264 codec form my system. Restarted pc. Installed x264 again. As a result of all this I had to completely reconfigure x264. I made sure that virtual dub hack is checked in the advanced settings, if I uncheck this I get problems with it crashing. Secondly, in the options tab where you can select the number of cores/threads for Dxtory to use. Made sure to leave those as default, some guides suggested using all the cores available but that seemed to cause more problems. // Edit - Upon getting home I see I have this set to all cores available on my system, apologies // Thirdly, and I don't know if this made any difference at all, but in my set up for the audio recording I had originally set it as record game audio to track one, microphone to track two. I accidentally removed the game audio so microphone went to track one, when I set the game audio to track two. I vaguely remember from a forum years ago that this can affect recording problems. And somehow after doing all these things it works again perfectly, no DayZ hanging, no failed recordings. I'll post some screenshots when I get home in a few hours. Stuck in the office at the moment.
