all.<br>
<br>
I use the latest version of VLC on OS X 10.8, on a
MacBookPro8,1 (i7 version) with 8 gig RAM. I regularly play
movies, each of which is about 1 gig of h264 at 720x576x25.
Sometimes I get my computer to do disk-intensive work (video
editing using Adobe CS) in the background while I watch my
movies. But when the video editing hits a part that's filled
with compositions/edits, the movie becomes choppy. If I pause
and then unpause the movie it gives VLC a chance to catch up,
but it sometimes becomes choppy again within a few seconds. I
wish that, while I pause the movie, VLC would cache further
ahead.<br>
<br>
If the bottleneck is disk I/O, is there some way that I can
tell VLC to cache more of the movie in RAM to avoid disk I/O
on the fly? If the bottleneck is CPU decoding, can I somehow
cache that, or tell it to degrade more gracefully than it
does?<br>

There must be an ionice command on your system, on Linux (Unix)
there is one. You can use it to set i/o priority of various
programs.<br>
