Jumpy video playback HD in VLC

[Messenger]

I received my Dell 2709w screen today, which is very nice btw, and wanted to test out the HD capabilities. Playing a 720p movie fullscreen results in a very jumpy, jittery playback during panning shots. "Still" shots are mostly okay.

Could this be a RAM issue, I can still add 1GB.

15" Macbook Pro, 2.33 C2D 2GB.
Screen attached with DVI-D cable.

Thanks for any insight!

Do you have an ATI card or a NVIDIA card?
im not sure which one is in that computer

If its NVIDIA there has been major issues with this card
if its ATI
could be RAM or V-RAM... just not enough

and lastly,

on your dell screen.
do u find the text size too big in browsers and things
cuz i would love the size of a 27inch
but i know that it only has a 1920x1200 resolution
a screen shot would be nice!

You need to tell us the file specs - encoding format, bitrate, fps, etc. You also need to tell us which version of VLC you're using. Have you tried XBMC?

Chipsetmodel: ATY,RadeonX1600
VRAM 256 (Is this upgradeable? Think it isn't).

VLC 0.8.6i (latest).

Videofile:
Resolution: 720*480 (Anamorph)
Frame Rate: 23.976 fps
Aspect Ratio: 16/9
Video Codec/Bitrate: x264 ~1344 kbps

The screen is beautiful, I don't find text to big, I have it at about one meter/3 feet distance. I just find it to big on the whole, since I've been working on my 15" mbp for the past year! I'm sure I get used to it.

This is likely your problem. That's a very low bit rate and in scenes where there's a lot of movement (i.e., rapidly changing pixels) you're going to see lots of artifacts.

Well bit rate can be low if the file is encoded well.

@OP: It's possible the video was encoded poorly. Did you try about video file?
