I've tried to download video or audio from this site http://www.meloman.ru/concert/70-let-velikoj-pobedy/#webcast using the hosting page link which has been got from Jacsta Media Recorder monitoring. But it was only 1 Mb downloaded from over 2.5Gb - what's the reason, could you talk me?
Are you able to play the video? Does it stop partway through, or does it seem to be the full length?
Can you send the log file to us? You can find it by going to the Preferences and clicking Find Log File.
