This issue does not affect all files and I have determined that this issue appears to only affect certain BluRay rips and is easily reproduced - I have tried several different files and have successfully reproduced the issue for most of them.\r\n\r\nSteps to reproduce:\r\n1) Produce an initial MKV file within MKVToolNix, configuring any options as appropriate. File size is 'x' bytes.\r\n2) Mux the file from step '1' using MKVToolNix without changing any of the default options (except perhaps the output file). If affected by this issue, the resulting file will be 'x+36' bytes.\r\n3) If the file from step '2' is affected by this issue, mux this file using MKVToolNix without changing any of the default options. The resulting file will be 'x+36+36' bytes.\r\n\r\nThis issue does not appear to negatively impact the usability of an affected file and is really an annoyance more than anything else. I am reporting this issue just in case an affected file is negatively impacted in a way that is not immediately obvious.\r\n\r\nCheers,\r\n\r\nJason.\r\n"}}
