Ubuntu - How to increase buffer rate on VLC?

I've got some high quality videos I want to run on vlc, but they require a higher buffering rate then the default for vlc. With the default the video skips every second or so and pixelates now and again. I've run the video on vlc on windows before and I found a buffer rate to change to make the video run smoothly, however, I don't remember what the value I changed was and when I looked through the ubuntu vlc options I didn't recognize it immediately. Any suggestions?

Is the file local or on a network ?
I did a similar thing and don't remember what I changed.

All the caching numbers are under Input/Codecs > Demuxers

I have had a similar issue with streaming over a LAN and my value for the Input/Codecs > Demuxers > Other Codecs > FFmpeg > Rate Control Buffer size seems ludicrously large for a default at 1835008

I also seem to have changed the tcp connection timeout in Input/Codecs > General to 5000ms but that is probably in an effort to reduce the network effect on my streams.

Most other caching value settings are under Input/Codecs > Access Modules with a default of 3000ms.

If you get some stuttering during playback, you can try to increase the size of the read buffer. This can be done in the Open Network Stream dialog box, by selecting the Caching box. You can then choose the amount time (in milliseconds) VLC should store data in its buffer before starting playback.
... you may have to check "show more options" at the bottom.

Does it really help with HD content? First thing i noticed when I came to linux was that it won't run HDs faster (but maybe slower)
