I record screencasts with other applications (not istanbul), and sometimes the high resolution (1024x768 and above) ones don't play on some machines. I believe this is down to a problem with the video memory/driver rather than istanbul itself. This is confirmed by the fact that you have tried multiple players - totem uses the gstreamer backend by default and mplayer doesn't. So I'd say that rules out totem and mplayer, the fact that I get the same with other non-gstreamer-based screen recorders says it's not the recorder either.
Can you confirm what video chipset you have? I have noticed this problem on machines with Intel video chipsets. -- No player can play screencasts recorded with Istanbul https://bugs.launchpad.net/bugs/120669 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
