Back on topic, I think something was recently modified (via a windows update) in the security settings for WMP. Keep in mind that x2 uses Windows Media Player by way of Internet Explorer for general rendering, and thus is subject to its quarrelsome security moods.
To wit, I noticed as well that some filetypes were not playing immediately - they were the more obscure-type (unsupported by WMP "out of the box") such as MKV's, etc, but considering they work fine in WMP itself I reckoned the codecs were kosher (and they were). Except they still wouldn't play.
Interestingly, the Quick-Viewer started popping up a notice (on those filetypes) regarding how "
The contents of this file do not match its filetype, Do you want to play anyway?" (even though there was nothing wrong with the contents). Selecting 'Yes', accomplished nothing - so remembering a
recent foray into the darkness, I went into the options of WMP (
Tools -> Options > Security > Zone Settings and unchecked "
Enable Protected Mode" just to see if it was the interfering party - et voilà - the files worked fine via the Quick-Viewer. Re-enabling the "protected mode" banjaxed them again, so it's going to be one of the million-and-one options under "Zone Settings -> Custom Level" that you need to play with - I have no idea which one.
Like I said, I think something was changed in a recent update, as WMP now seems far too sensitive when checking filetype content when invoked through a 3rd-party embedding (such as the Quick-Viewer), and it fouls it up.
Try (temporarily) disabling the "protected mode" checkbox to see if it is indeed the offending party on your system as well, and if so, then you know where to start digging to find the bodies.
