Before I abandon using JRiver on Ubuntu altogether, can someone tell me if there is a way to get the playbar from vanishing when I hover the mouse over the top of the screen while playing back a video? I have no problem with that on Windows 7. I point the mouse at the top of the screen and the playbar appears. From there I can click on any of the options that appear such as stop, pause, or next video. I can change the volume or jump to a different position on the video. Also, one click on the scroll wheel will jump the video ahead 30 seconds or back by 20 seconds. None of these features appear to be available in JRiver on Ubuntu, so the only way to navigate through a video is through the keyboard. I'd like to keep using JRiver on Ubuntu but the lack of these features make it less then usable for me.
