Choppy playback of DVDs and large videos

[sjm@…]

Watching normal sized videos is OK but still seems somewhat "not right" (I would
put this down to placebo effect if I hadn't thought it before watching a DVD)
but watching large videos and DVDs is a no-go. The xv driver is extremely choppy
(lots of image tearing) and the x11 driver is less choppy but has a weird aspect
ratio bug whereby the window itself is 16:9 but the image is 4:3 with
transparent borders down the side. The sound seems to stay largely in sync with
the video.

I have an AMD64 3200+ with 1GB of RAM so that shouldn't be a problem. I don't
experience this problem under Linux and the OpenBSD Ogle port plays DVDs fine.

xv problem seems a driver bug, nothing we can do (unless it's just that vsync
attribute was not enabled, then it should be fixed). Reopen if you have any
indication this actually is a MPlayer bug.
Problem with -vo x11 can be avoided by -zoom, which is slow though since it
uses CPU to scale to correct aspect.
