K2 is great and I am converting all my sites to use it instead of the Joomla default. I am creating a site for a musician and the only thing I wished it had was the addition of the audio tab to upload mp3s. The Allvideo plugin supports it with the {mp3} tag but I don't know why it was not included as one of the media options when creating the video tab. I tried to see if I can figure it out but it is way over my head.

Also, it would be great for an option to choose from a video and/or audio file already uploaded by FTP to overcome the php restrictions on upload size. Either way, I am sold on K2 and will not go back to the Joomla default content.

Completely Agree with you "Manukat "
No full catalog without contents you mentioned above.

Do it already! :) If I knew how I would.
Would make this component awesome!

How long will something like this take?
I am building a site now that requires these functions.

You can create an audio tab by copy/paste other tab then adding a textarea to embed the audio w/ the Allvideo code.
{mp3}nameaudiofile{/mp3}

Also you can add audio to your k2 content by adding Allvideo code. {mp3}nameaudiofile{/mp3}
