Apologies for the painful noobishness of this question, but I've only been using Usenet and Sabnzbd for about a week. I've been nosing around the Wiki but I don't quite understand the terminology yet. So ...
Do missing articles matter? I noticed only recently in the Sabnzbd browser that some videos which were successfully downloaded have messages about missing articles. The size of the downloaded files appears to be correct, and playback seems OK after a quick sampling (I haven't yet had time to watch the entire video).
Should I expect videos with missing articles to fail? Or can I have confidence that if Sabnzbd downloaded the file, did quick-check and repaired it that it should work OK (assuming of course that the source video itself doesn't have errors)?
Thanks
UPDATE: Here's a screen grab of a file that I just downloaded. What do these messages mean, and should I be concerned, even though the file passes Quick Check and repair?
