...fix some video portal issues...
You can set subtitle options using Chrome or IE, but you can't view subtitles in IE.
When you upload a video, it's default name is the filename, but this can be changed. If you want to overwrite this video with an updated one, you can do so ONLY IF you remember what filename it was uploaded as originally. How do I find that out? It's not shown anywhere.
I uploaded a new video. The option to change the thumbnail was not present. I went to a previous video where I did change the thumbnail, and saw the option. I went back to the video where I did not see the thumbnail option, and now I saw it. I encountered this problem a second time, did the same thing, and then the option to change thumbnail was available
