    kdenlive hangs w/100% cpu usage. Was working before upgrade to 9.10

    OK, I upgraded from 9.0.4 to 9.10 when it came out... and had used kdenlive 0.7.5 without any issues on 9.04.
    I tried to use it after upgrading, and it's not working.

    I've tried loading previous projects, and creating simple new ones, but the same thing happens (even with an empty project). When I Play the project in the Project Monitor, it just hangs and the CPU pegs at 100%. It doesn't recover, and I have to kill kdenlive.

    I thought upgrading to 0.7.6 might help, andI was able to do that using the method outlined here: http://kdenlive.org/user-manual/down...buntu-packages

    But I still have the same problem. I didn't see this problem before, and it's not for lack of hardware - it's running on an Intel quad-core with 4 Gig of memory.

    I am wondering if it is somehow related to audio, only because I had issues with getting audio to work correctly with some apps after the upgrade to 9.10. But I played around with the audio preferences in kdenlive, and it didn't seem to help.

    Kdenlive 0.7.6 on Kubuntu 9.10 with KDE 4.3.2.

    Did you had similar problem on previous versions of Kubuntu ? (Previous than 9.04)

    Try to change brightness of your screen by clicking battery icon next to clock or brightness in system settings.
    - Is anything suspicious happening ?
    If you have laptop try function keys to change brightness.

      I didn't use kdenlive prior to 9.04...and the rest of your comments confuse me. No, it's not on a laptop.

        Well... kdenlive is now working, although not 100%. I get no sound.

        Sound has me pretty frustrated in this release, it works for some apps but not others, and seems to cause lots of problems. See my totem post here: http://kubuntuforums.net/forums/inde...opic=3107557.0

        Now I just have to get sound working in kdenlive so I don't have to render a video just to play it back and hear it.

          Well, as I tried to fix this, Totem and games started going silent... I finally found this:

          Step 1 solved my problems... I have Totem, games, and kdenlive with sound all working. *phew* Let's hope it lasts.
