Just installed PotPlayer after you suggested it. Installed as non-default video player but it seems very likely that I'll ditch VLC and use this instead. I've had problems in the past with keeping the 64bit version of VLC up to date.
I get my
64-bit version updates of PotPlayer from DVBSupport (rather than from the developer's Korean web site, although they do have an English version of the pages).
As easy as PotPlayer is to use by default setup, it also has an enormous amount of customizability. And of course it can be set up to be the windows default player for a huge number of audio/video formats if you want.
Also, with its preferences ("save settings to INI file") you can preserve your customizations across version updates. Unfortunately each new reinstall will reestablish the default settings, so in theory you need to re-customize each time (including even the need to re-check in preferences that you want "save settings to INI file").
That's of course crazy if you ask me, but nevertheless that's how it works. So using the INI file approach allows you to revert back to all your prior customizations just by closing the program, and deleting the newly created default INI file, and renaming your old saved INI file (which has been renamed to .BAK) back to .INI. And now when you re-open the program you're back in business using your original INI file reflecting all of your customizations (which also get merged with any new preferences options that might have been born in the version upgrade).
If you want to try my INI setup, let me know and I'll PM it to you.
I especially like the "windowless" option for presentation, where there is zero outer window around the image being presented. Just seems to magically float on your desktop, and also therefore supports viewing 1920x1080 in absolute full-screen perfect resolution (if you have a 1920x1080 monitor) with zero scaling required. The player controls at the bottom of the player will magically appear if you hover the mouse over the bottom of the image, and will disappear again when you move the mouse away. Very pretty, if you like it that way.
On VLC, It rocks
