Hi folks,
I've been using kubuntu for a little while now and, so far, am having great fun with it. I just have a couple of problems I haven't been able to track down. Here's the most annoying:
Briefly, when I play back a video I get two problems:
1) Every 10 seconds, the video freezes for about 0.3 seconds - one frame stays displayed for longer than it should be, then the video stream jumps forward to where it should be. The audio track plays back smoothly. The timing is a bit odd here - the first jerk happens 7 or 8 seconds after playback starts, then all further jerks are exactly 10 seconds intervals afterward (measured by watching video software's clocks).
2) Whenever there's a lot of movement on the video (e.g. someone walking across the screen, or the shot panning around a room), the top section of the screen gets out of sync with the bottom. This is hard to describe, but the bottom section of screen seems to be lagging a few fractions of a second behind the top. There's a sharp division between the two sections (i.e. no blurring or gradual transition), but the relative size of the sections varies. It can be anywhere from the top 20% to 50%.
Both problems happen with all dixv-encoded .avi files (e.g. EZTV's releases of Lost, BSG, Heroes), all DVDs... basically anything I can use to play a video on my laptop. The only exception I've seen are flash-based players like youtube and BBC iplayer (which I don't run fullscreen).
Both problems happen in windowed mode, maximised window and fullscreen modes, although are most noticable in fullscreen mode.
Both problems happen with vlc, totem, "Movie Player" (mplayer?) and kaffeine.
I'm running kubuntu 8.10, with all the latest automatic updates applied. Turning Desktop Effects off (via System settings > Desktop) or swapping them from OpenGL to Xrender doesn't make any difference.
My computer is an Acer Aspire 5610z. (Centrino 1.66GHz Core Duo, 1GB RAM, Intel 945GM shared graphics). In the bios my shared graphics memory is set to the highest setting, 'though I forget the actual number. So this isn't exactly a beast but it should be able to play a video file, right?
I ran "top" through Konsole. The system looks pretty untaxed:
...so I'm pretty baffled. Can anyone help me work out why my mostly-idling system sucks at playing video files?

. So I've no idea what the root of the problem was, only that it has gone. Yay! Another heartfelt vote of thanks to the good folks who write all this free software.
