The app mvideoplayer keeps saying there's an update available, (which we all know can be annoying in our notification bar) but everytime I attempt to update it fails saying "package file was not signed correctly". Now I don't even know what that is, whether its on my end or the apps? Anybody know what this means and maybe how to fix the issue?

That's an issue on the developers side... each time a developer publishes something to the market they have to sign or verify an app with a certian alias and this error can crop up if they swtiched alias at somepoint in development eithr between updates or if they reuploaded the APK file. There's nothing you can do about it on your end save from sending the developers an email letting them know that they need to resolve the issue. But it's not a huge deal and most developers can solve the issue quite quickly, so I wouldn't worry too much about it.
