RMVB files disappear when over 100% resolution

When I try to run an rmvb file and I extend it to over 100% the image just disappears after that, is there any solution?
Answer #1
Try Real alternative or Media Player Classic. Both come inbuilt with K-Lite Mega Codec Pack which I would suggest getting if you’re not using anything else. You can get the latest version here:

Good luck mate ^_^
Answer #2
I’ve figured it out when I downloaded that, now the problem is that when I try to make the resolution larger than 100% it just totally disappears which is the same as the original problem :/
Answer #3
Nice edit
Well, try uninstalling all codec packs that you have on your PC. Then install one of your choice, for example CCCP or K-Lire Mega Codec Pack. See if it changes anything. If it doesn’t then try using VLC to play your files. It’s a freeware so you can get it by searching Google. Good luck mate ^_^
