I'm running into the same problem with the 2.1.2 wp install.
I uploaded one .jpg, one .mov, one .avi, and one .pdf, just to see what I could see (since my initial attempt to see an uploaded video file failed), and only the jpg showed up. So I went over to Options>Misc and checked the "Organize my uploads into month- and year-based folders" box and voila! I can now see the avi file. But the others still don't show up.
I really don't want all the extra folders to be created, I don't see the real advantage of it, since I don't plan on uploading much. But I'll do it if I have to.
I'm ready to hard code a fix if I have to. Just somebody tell me where and how. I want to be able to view and at least copy and paste the full path of every file I put in there.
I've searched and searched plugins and support for an answer to this. I also want to imbed video files from my uploads folder into my blog. I would like it to be totally easy for non-techy person to use. No extra software for "converting" normal avi, mov, or mpeg file to something else (whatever player the plugin uses should be able to play popular video formats), and less guesswork for selecting and imbedding files in the post. It's for a family blog, and I want my sister to have some chance of figuring it out.
Wordtube has a great "add your video/music file to post" interface (you can browse the upload folder & select!), but it requires you to download a separate player AND a program that converts popular video formats to one that can be played by the player. Anarchy Media Player uses a flash player that plays popular formats, but you have to know the path of the files (cause you can't see um!) and know the pixel size - which would Never work for my sister!
