Hi,
I have a ton of .avi files. Ever since my last ubuntu online update, they can't play at full screen even though they played fine last week. I tried reinstalling mplayer. No difference. Same problem with xine.

They freeze for about 1/2 second at at time and chop their way along. Not even viewable. But, they look fine in mini-mode.

I have 4 gb ddr3, a quad core, 2.83 gzh intel and an ati 4850 / 512 mb video card. CPU on gkrellm shows < 10%. I think I still have the proprietary ati drivers because I can still move my applications around the screen instantaneously. I have tried xv, gl and gl2 under mplayer -> prefs -> video. All are the same.

Everything works perfectly if I reboot to xp :-(

Where does one begin to debug this?

Thank you,

BrianP

install smplayer
open a terminal type smplayer
it tells you how to install it

have the same problem on/in 804
they play fine with smplayer right click open with
after the first time they will open in smplayer

this way you can watch them
so if they dont fix mplayer for a long time

hope this helps

I had similar issues with mplayer and xine (using smplayer and kaffeine, respectively). However, the problems just went away, and now both work. I still have problems with vlc, which is why I don't use it. However, if neither mplayer nor xine are working for you, perhaps you'll have better luck with vlc.

Of course, as no2498 pointed out, sometimes a good frontend like smplayer can help with the backend (mplayer, in this case).

Otherwise, try "sudo dpkg-reconfigure mplayer" and see if that works (using the actual name of your mplayer package, of course).
