I had the same problem. I saw the solution on another site and it worked for me. The 1080p file actually played fine in windows media player, so I knew it wasn't my computer. The solution is to change the file cache to a larger value, say 2000, in vlc player. You can find the setting in tools/preferences with "all" checked in show settings. Then go to Input/Codecs, where near the bottom of the window it says advanced/file caching. Set it to 2000 and save, then restart VLC player. Wahla, it worked for me. It took me a second to find the show settings at the bottom, and then it took a little while longer to find the file caching, but once I found it, it worked perfectly. You might also want to reset VLC player, just in case you messed it up really bad, and then increase the cache value. Good Luck.
