Hi,
Well since this value is also present in recorder config file my guess is, that changing this value would not help, because from my understanding you are facing this issue in playback itself, but not in recorder. Best way will be to open support case for your issue and support will help you in collecting log files. If website you are trying to record is publicly accessible and this will be no secure issue to you, you can add problematic *.recording files to diags. This will help us in investigation of your issue and make the process of investigation faster.
