I'm currently uploading two HD videos to SS. According to the status in Stocksubmitter, the clips are submitted and there is the green circle that indicates exactly that. And I have logged into that catcha thing for SS that pops up within Stocksubmitter.
When I log into SS on Google Chrome, there are 0 pending video files. And 0 clips for 'not yet submitted.' In other words, there's no sign of these files on SS.
However, last night, I had no issue submitting a video file to P5 via Stocksubmitter. That clip is pending review within P5.
