Kaltura Joomla experiences so far

Firstly thanks to the developers for integrating this great package with Joomla. It really is a great platform & results in great looking videos.

I'm having a few issues at the moment:
- within joomla I can only upload 1 video at a time & I can not finish the upload process i.e. pressing 'OK' at the last stage of uploading does nothing. (both FF & IE). I'm able to embed the videos by copying the code from the Content Manager then entering this into the Joomla Editor.

- uploading in the Content Manager causes a browser crash in both IE & FF.

- it would be wonderful to have the option of a vertical display in the Application Studio. I've tried this:

but must have done something wrong. Is everything supplied in this guide? e.g.
"# As you can see, the

These could very well be issues at my end. Any help would be greatly appreciated. The degree of control & end result from Kaltura does look awesome.
