Version: 6.2.6.4 (x64) Module: HBO Max Content: The Chair Company - S01E03
Issue Description: I am encountering Error 702 immediately after the download phase finishes, during the Remux/Muxing phase.
After analyzing the logs, this is not a network timeout. It is a syntax error in the command line arguments passed to mkvmerge.exe.
The episode title is: “@BrownDerbyHistoricVids Little bit of Hollywood? Okayyy.”
Because the title starts with the @ symbol, mkvmerge interprets the string as a response file (a file containing command line arguments) rather than a string title. Because that file does not exist, the process crashes.
Log Evidence: Please observe the cmd line and the subsequent open file error:
2025:11:21-02:27:31 [Info]: [default] “[CefMedia] RemuxMultiAudioSrtMetaUtil pid 16200 cmd: \”…/mkvmerge.exe\“ -o \”…/The Chair Company_S01E03.mkv\“ –title \”@BrownDerbyHistoricVids Little bit of Hollywood? Okayyy.\" …
2025:11:21-02:27:31 [Info]: [default] “[CefMedia] Error: ”
2025:11:21-02:27:31 [Info]: [default] “[CefMedia] The file ‘BrownDerbyHistoricVids Little bit of Hollywood? Okayyy.’ could not be opened for reading: open file error.\r\n”
Suggested Fix: The application needs to sanitize the –title metadata string before passing it to the muxer. Please escape or strip the @ symbol if it appears at the start of a string to prevent mkvmerge from treating it as an operator.
