uploading videos is successful but browsing interactive video doesn't show me the uploaded and processed files

Hello,

Well everything is in the title.
Using KalturaCE 1.5 linux x64 and wordpress plugin 2.2.
When I upload files it works great. Then when the file are processed and I'm going in the browse interactive video, I can see only the mix (created while processed, why this? and btw the mix doesn't work, I just have one frame or so) and cannot see any single video.
Same from the admin page of all in one video pack.
If i remove the mix, then I have the empty page displaying "No interactive videos created yet"
Any idea?
I can embed the code into wordpress, getting him from the kalturaCE server content, but I would love having this working...

Also, it would be great when you are releasing the server to specify which version of the plugins are compatible with it.
Maybe it's done somewhere but couldn't find it :)

If you need more info please let me know.

Cheers.
