Description

when I want to download a course from teamtreehouse.com, the first and the second video download without problems but the third item on the course actually is not a video it is a review questions so the youtube-dl does not recognize it and when it finds out there is no video on that link this error occur that I provided it above and the program stop downloading the video following that link that does not contain any video, I hope to fix that soon by skipping those links that does not contain a video
this image shows that the third item does not contain any video but it is review questions

-i, --ignore-errors              Continue on download errors, for example to
                                 skip unavailable videos in a playlist

[apache123]

thank you so much, but now the the title number is not ordered it skipped number 3 and other numbers, how can I fix that.
I mean the order of numbers I want it to be 1,2,3,4,5,6 but it is 1,2,4,6,8,11
I use this formatting option
-o "~/Users/apachee/%(playlist)s/%(chapter)s/%(playlist_index)s-%(title)s.%(ext)s"
