hello, i have a problem.

i usually encode x264 brrips with staxrip from 1080p/720p to x264 mkvs with crf 20.

i use dolby digital 5.1 , 448 kbps and 48.0 khz at audio options..but sometimes i have no audio after some time, like 39:21 i have no audio anymore at my encode but the original 1080p encode has at this point audio, you know why?

greets
