Interlacing problem

[gksdfjghe98]

I'm not entirely sure if this is a GFX card problem or a Monitor problem so if I've posted it in the wrong forum I apologise.

I'm having problems with video playback on my system because of a horrible 'scan-line' effect from what looks like interlacing. It's not a massive problem as movies are watchable from a distance, although this is my monitor so 99% of the time I'm up close and personal. I don't get this effect while playing games. I'm not exactly sure what is causing it and I can't seem to find anything on Google that addresses a similar problem so I could simply have something configured incorrectly.

Relevant specs:

• 2 x XFX Radeon HD 4890 (in Crossfire)
• Hyundai W240D 24" Monitor

The monitor is connected via HDMI using the adapter that came with my graphics card. I have tried disabling crossfire and changing resolutions and I've had a quick gander through the Catalyst Control Panel but I haven't seen anything that I understand would fix it.

Any input is appreciated. Attached is a screenshot of my Windows Media Player in action. If you need any more info, just ask

Its only on video playback? That would suggest to me that its some sort of codec problem

I'll get some codec packs and re-evaluate the situation. Hadn't thought of that. I'll update when I've done so.. There's a problem with my exchange at the moment so my internet connection is half-arsed and comes and goes as it pleases. Cheers.

--Edit--

Seems to be working a lot better now. The help is much appreciated!
