WITH XGL: video fine. WITHOUT XGL: video skips wildly.

[SideshowMel]

i've been having problems playing .avi XVID files in Fedora 7 when logged into Gnome or KDE while NOT using XGL. With Gnome+XGL or KDE+XGL, it looks fine, but without XGL, it "skips" or "jolts" around in the viewer (difficult to describe).

In discovering a work-around, I have run in to a new problem.

My work-around is this:
If I login to a Gnome without XGL session and try to play my media file in VLC, if I go to Video > Deinterlace > and select "Blend", it looks fine!

My new problem is this:
In the VLC preferences, there is a section under Video > Filters > Deinterlace where you can set the mode to "blend," but that settings doesn't seem to work. I have to change it to "blend" manually each time I want to watch the media.

How can I make sure all video is set to "blend?" Does anybody have any ideas as to what could be causing this problem based on my work-around.

Thanks.
