When i use xine I cannot control it, Sound, Video, ETC...
There is a long lag time when I try to stop playing, Pause or change a setting. sometimes I have to reboot to get a video to stop playing. Is this a video problem or something else?
This is really frustrating........

Try MPlayer or VLC
I think it's much better replacement than XINE

Tough to say without more information. Could be a video card or driver issue. A quick test is to rename the user configuration directory $HOME/.xine. Then start xine. Xine will create a new instance of the directory.

Xine comes with a simple system check utility called xine-check. Open a terminal window and run the script.

Another test includes using other media players. You seem to be using Slackware 12. If I recall correctly the stock Slackware 12 did not come with additional multimedia players.

Checking slackbuilds.org shows there are several build scripts for media players for 12.0. Kaffeine is a KDE 3 app that defaulted to using xine as the back end. You could use Kaffeine to possibly determine whether the problem is the xine user interface or the backend engine. Mplayer and VLC are additional options to test the same videos.

You rarely should need to reboot to stop any app. Open a terminal window, run the ps command to find the process causing problems, and then terminate the process.

For example:

ps ax | grep xine | grep -v grep

That will reveal the process ID of the xine app. Then terminate the process:

kill -9 [process id]

I will try to install video drivers..... :::))
