Installing Ubuntu in virtualbox
Download virtualbox and extensions

Choose Hard Disk size. I chose 15 GB and “create virtual hard disk file.”
Choose Hard disk file type. I left it at VDI.
Choose Storage on physical hard disk. I used fixed size because it faster.
Choose Location and size. Ubuntu
Choose Virtualbox – preferences – extensions and install the Virtualbox extensions you downloaded. The extensions enables USB 3.
I upgraded the settings on the Ubuntu virtual machine:

Running Subtitle Edit in ubuntu.
You can run portable Subtitle Edit in linux. There is a discussion on the sub talk forum on how to run it.

You need to install mono-complete and Mplayer.
