When I try to play mp4 files through xbmc the audio is fine but the video is skewed and repeated along the top quarter of the screen. Does anybody else experience this problem, is there a fix?

Mine play fine. Do other media players show them okay?

Yeah they play fine in both vlc and mpc-hc. I'm running Windows 7 x64.

I'm gonna take a guess and say you have an AMD/ATI GPU. If that is the case search the forums, as there are threads discussing how to deal with such issues. First step is to make sure you have current graphics drivers.

My graphics card is an Nvidia Geforce G102M, nothing special, just came with the laptop. I did look for threads about mp4 incompatibility but couldn't find anything that addressed the problem. I will try and and update my graphics drivers though, thanks.
Again, any help is greatly appreciated, even if it's just to say that you have no trouble playing mp4s. It would be nice to know whether this is a widespread problem or not.
Thanks,

Wow. I've not heard of that issue with an Nvidia card. AMD/ATI GPUS have exhibited strange issues such at that in the past. XBMC can play .mp4 files just fine. Start with updating you drivers. Then we can go from there.

What are your video playback options set to inside of XBMC? It might also be good to post a log with debugging enabled. Post it to pastebin and link it here.

On the basis of your last post I just tried disabling 'Enable Hardware Acceleration' and now my mp4s play fine! Probably should of tried a few things before taking to the forums but hey, thanks so much for your help kricker! I'm not sure when or if i'd need hardware acceleration or how much difference it makes when it's enabled, that's for hd playback or something isn't it? Hopefully turning it off doesn't affect any of my other files too much. Anyway, thanks again kricker, problem solved.

DXVA2 is used by certain GPUs to allow them to do the heavy lifting and lower CPU usage for HD playback. Your GPU has to support this as well as have proper driver support for it to work properly. When enabled and working properly you will see your CPU usage drop very low for 1080p HD playback. You may still be able to use the DXVA render method, just not DXVA2 acceleration.
