I hope I have not rushed into reporting too early. Running 2013.10.15, on a windows box, through the cmd shell.

Can you post the entire output of youtube-dl when given the -v option? Without the playlist ID, options, and version information, it's impossible to reproduce this issue.

Updated the first entry as requested by @phihag.

More information.

Particular subtitle object may not be found in YT.

Problem can be ignored by the documented ignore parameter (-i), therefore this issue is not critical (or whatever the appropriate term form non-critical issues in github is called). But I believe the output should be more graceful, i.e., "Subtitle can not be found", instead of outputting trace-back, unless called while verbose, or debug mode enabled.

For whatever reason (most likely a coding error or YouTube filesystem failure) , this video does not have automatic captions (the web player hides the button as well after clicking it).

Update to youtube-dl v2013.10.17 or newer (by typing youtube-dl -U as soon as the release is rolled out everywhere, which should be a couple of minutes) to fix this issue. Thank you for the report!

Thank you for immediate response. Wish you best contributions...
