Hi,
I'm very sorry for the slow reply. Its very easy to modify the current x3 play speed to play at 10x speed. All you need to do is:

Download the sourcecode from https://launchpad.net/cowlog/+download. Open CowLog.py and replace the following lines (72-):

playbutton3 = QtGui.QPushButton(QtGui.QIcon("icons/play.png") ,'x3′, self.mainWidget)
self.connect(playbutton3, QtCore.SIGNAL('clicked()'), lambda speed = 3: self.play(speed))

with:

playbutton3 = QtGui.QPushButton(QtGui.QIcon("icons/play.png") ,'x10′, self.mainWidget)
self.connect(playbutton3, QtCore.SIGNAL('clicked()'), lambda speed = 10: self.play(speed))

So you actually only need to change the button label from x3 to x10 and "speed = 3″ to "speed = 10″. Be sure to preserve the indent though.

After you make the changes you can run CowLog.py, but remember you'll need to have Python and PyQt4 installed.

I'm very interested in using your CowLog program, but I noticed that you are only able to playback video recordings at 5x the normal speed. For my research I'm studying rattlesnake behavior, and since these snakes are sit-and-wait foragers I have thousands of hours of recording that I need to review. Now I know this forum is for "Proposed Features", but since this is opensource software I'm wondering if it would be possible for me to increase the playback speed (instead of waiting for an updated version). I have no experience writing code (and I'm not trying to ask for help), but how difficult would it be for me to rewrite this portion of the program? Any comments would be appreciated.
