VLC Player stutters!

[xiga]

Hi guys,

well, I'm new here (and totally loving the forum!) and just thought I'd run this one pastall of ye and see if we can't get it sorted between us.
I've installed VLC Player (latest version) and for some reason it simply won't play ANY movie files properly. There's this constant 'flickering' (for lack of a better word) and it's all the more strange seeing as AL Show and Media Player play all my movies just fine (I want to stream movies from my PC to my Dbox downstairs and apparently you have to use VLC Player for that).
How powerful a computer do you need to stream movies this way? Here's my rig (2 years old):

AMD Athlon XP 2800+ (o/c to 2.2GHz), 2.5GB Ram, XP Pro, Geforce 6800

Not fantastic by todays standards but surely powerful enough for this purpose I would have thought?

Could it be a codec issue? I'm running an older version of the Forceware Driver (84.21 I think) as the newer ones caused even bigger problems and this one has always served me well so I rolled back. I'm also using the K-Lite codec pack.
I#ve probably installed (and uninstalled) a lot of drivers/codecs over those 2 years, is there an easy way to clean it all up, leaving only what's needed, and none of the crap?

Any opinions fire away guys.

Cheers.
