On a general note for cases like this:

Look at it like you want to reproduce the problem yourself only with
the info you provided. (read: If unsure, look at it from the
viewpoint of a complete stranger who doesn't know what you are
talking about; now exactly a numbnuts walkthrough, but you get the
idea)

I don't think this is loop-AES related. You could start
resource-hogging applications with a nice level of 10 or somesuch and
see if it affects things positively.

Now you talk about session locking requests... In context of video
playback, the first thing that comes to mind is a bad video file;
borked index. Whatever file you want to play, open & save it in
avidemux first to check its integrity. It also could be a codec issue
(namely mp4 & mov, wmv occasionally).


Such overwhelming lagging happened to me and it was due to low memory
- perfectly reproduceable: fire up KDE, open a large pdf (2/3 of
total RAM is sufficient), and start a text-search... eventually the
system's OOM killer strikes, after a prelude of minutes in which the
system is unresponsive/lagging at best. I'm still using a laptop with
only half a gig of RAM.

HTH a bit ...
