Bought script, few questions now ...

Hi Friends,
I bought this script yesterday but i don't understand how to do the following things. I would really appreciate if someone can help or give some clues.

1. How can i create sub-categories? I think this feature will be in 2.7 release, so any idea when that release is coming out?
2. Is there someway, I can disable the upload function and just allow only the second option i.e. hotlinking from other sites like youtube. I do not want to host any videos on my website.
3. Finally, when i import the video from youtube, the thumbnail is not generated for that video. Can the script generate the thumbnail automatically for each video imported from youtube as done by this open source project (http://phpdirector.co.uk ).

Please help
Thanks

1.We are working on Sub Channels, will be available in 2.7

2.In upload page two option

1.Your PC

2.Remote Server

You can delelte the your pc option from upload.tpl fle from template folder.

So the users need to upload videos from the other sites

3.If you import video from youtube it will automatically create thumnail also
