FC2: Big problem playing DVDs and video clips

[Motor]

System specs:
Matrox G550 (32mb ram)
AMD Athlon XP2000+
512MB RAM

This computer was upgraded from Fedora Core 1 to Fedora Core 2. I deleted the old XF86Config file and let FC2 set its own xorg.conf.

Everything seems to work except for playing video clips and DVDs when the output is done via the XVideo extension. Some low resolution video clips will play, but anything larger causes problems. It fails with errors in the XVideo code when trying to play DVDs with both mplayer, and ogle.

This all worked fine in FC1, but I do remember a similar problem with an earlier RH (and XFree86) release. I can also reliably cause lower resolution clips to fail in the same way (which would otherwise work) by running XMMS first.

Can anyone help?

Example:

>mplayer -v dvd://2

Try using a different video output. It might work.

It works with different video output (I tried it before), but this is a fault in FC2 (possibly xorg-x11). I posted a bug in RH's buzilla a few days ago only to have it dismissed as a problem with mplayer despite the fact that xine, ogle and mplayer all fail.

I'm been discussing it on the fedora-list mailing list too, and have narrowed it down a bit.

Sorry for following up my own message, but here's some more info and a workaround for anyone who suffers from this problem has tried searching this site, and ended up on this thread:

The bug is now being tracked in freedesktop.org's bugilla:

http://freedesktop.org/bugzilla/show_bug.cgi?id=474

And relates to pixmaps being cached, but not cleared out when the memory is needed for the XVideo extension. There is a workaround suggested in the bugzilla page, adding:

Option "XaaNoOffscreenPixmaps"

to xorg.conf, giving something like this:

Section "Device"
Identifier "Videocard0"
Driver "mga"
VendorName "Videocard vendor"
BoardName "Matrox Millennium G550"
Option "XaaNoOffscreenPixmaps"
EndSection

This seems to work for me... though obviously it is just a workaround and not a solution.
