VLC "snapshot" problem - help?

[MinionZombie]

I'm having a problem with VLC - specifically the snapshot function (which used to work just fine for me) ... it's an odd thing, and I'm not sure what could be causing it. Everytime I take a snapshot, it comes out with this jagged lining around certain edges - as seen in the example below - any ideas on how I can solve this issue? I need to get screenshots from recent films I've edited for the website on which they're sold - and as I've said, VLC hasn't given me this problem until now - no matter what computer I'm trying it on.
