We tested alugha already on different Linux systems, BSD, Mac OS X, Windows Vista/7/8 and at all of them on different browsers as well. We can say that all modern operating systems are good for alugha.
We would be more than happy if you could share your own experience as a video producer or as a user in case of alugha. Which browser on which operating system did you use and what was/is your experience here...
Thank you for helping us with your report! Please state the error you found within the video and we'll check out what's bugging you.
